With teams having already started or starting spring practice over the next few weeks. there are a lot of players across the country who will be charged with replacing someone who has come and gone before them. It's an annual rite of spring in college football, when the senior quarterback from last season is putting the finishing touches on his final semester as a college student, and the sophomore who isn't even sure what he's majoring in yet realizes he's going to be majoring in Playbook 101 for the next few weeks.
Of course, while roster turnover is a common occurence in college football, there are bigger shoes to fill than others, and in this post we take a look at the ten biggest pairs looking for a new owner this spring.
10. Ryan Broyles, WR, Oklahoma
Ryan Broyles began re-writing the Oklahoma record books the moment he stepped on the field in his first game as a Sooner. He caught 7 passes for 141 yards against Cincinnati, both of which were freshman records. Four years later he finished his career having caught more passes than any other receiver in FBS history, pulling in 349 passes for 4,586 yards and 45 touchdowns.
In other words, he's not the type of player that Oklahoma can just replace with anybody. This spring receivers like Kenny Stills, Jaz Reynolds and Trey Metoyer will try to replicate Broyles' production in Norman. Whether it will be one of them doing it, or a group effort, Oklahoma will need it to happen if the Sooners want to win the Big 12 and contend for a national title.
9. Matt Kalil, OT, USCUnderstandably, USC fans were extremely excited by the news that Matt Barkley would be returning for his senior season, and many have pegged the Trojans as a title favorite because of it. What you don't want to do, however, is overlook the fact that the man who was in charge of protecting Barkley's blindside these last few years won't be back.
Though that's how life generally works for offensive lineman like Matt Kalil. As large as they are, they're often overlooked. Kevin Graf, Jeremy Galten, David Garness and Nathan Guertler will all be competing for the unenviable task of being the man in charge of making sure nothing happens to the most valuable piece of the USC offense.
8. Mark Barron, S, Alabama
One of the problems with having a defense as strong as the one we saw in Tuscaloosa last season is that you're bound to lose players to the next level, and the Crimson Tide have no shortage of beasts making their way to greener pastures. Still, the Tide have a knack for churning out defensive lineman and linebackers, but safeties like Mark Barron don't come along all that often.
Barron made 231 tackles for Nick Saban in his four seasons, including 13 for a loss, while picking off 12 passes. Barron was the type of player that could defend the pass and the run, and he won't be easily replaced. Can Robert Lester or freshman Vinnie Sunseri step up and be the next stud in the Alabama secondary?
7. Luke Kuechly, LB, Boston College
Based purely on production, there may be no larger shoes to fill in the country than Luke Kuechly's. There may not have been more than 3 plays run by opposing offenses in which Kuechly wasn't in on the tackle. Kuechly finished 2011 with 191 tackles. The next highest total on the Boston College defense belonged to Kevin Pierre-Louis, who had 74.
As our own Chip Patterson put it, "for Boston College, replacing Kuechly is like any other team replacing 2 1/2 players." Though it's been proven that it can be done, as Kuechly himself once had to fill the shoes left behind by Mark Herzlich. Pierre-Louis and Steele Divitto -- who has a name that would be hard to replace -- will be the two linebackers looking to repeat the feat.
6. Morris Claiborne, CB, LSU
Many casual college football fans never truly appreciated how amazing a player Morris Claiborne was for LSU in 2011 simply because opposing offenses weren't dumb enough to test him all that often. Throw in some Honey Badger exploits with a bit of Les Miles being Les Miles, and Claiborne gets a bit lost in the gumbo. Still, Claiborne truly was the definition of a shutdown corner for LSU, playing a pivotal role on one of the best defenses in the country.
While Tyrann Mathieu will be back in 2012, he's not the cover corner that Claiborne was, so it will be up to Tharold Simon to fill the role. One he seems capable of considering he led LSU with 10 passes broken up in 2011 playing mostly as a nickel back.
5. Trent Richardson, RB, AlabamaI won't lie to you. Even when Mark Ingram will still in Tuscaloosa running through SEC defenses, I always felt that Trent Richardson was the best running back on the Alabama roster. Now both are gone, and Richardson will be harder to replace than Ingram was simply because Trent can't replace himself.
Can Eddie Lacy be the next Heisman finalist in the Alabama backfield? He showed some promise in 2011, and in an offense like Alabama's, the opportunities will be there. Still, even if Lacy is extremely talented, there are only so many shoes capable of doing this.
4. Brandon Weeden/Justin Blackmon, QB/WR, Oklahoma State
A bit of a cheat, I know, but the truth is that Brandon Weeden and Justin Blackmon felt like extensions of one another for the past two seasons in Stillwater. Their success was as a duo. I mean, Blackmon caught 40 touchdowns over the last three seasons, which accounted for 53% of the 75 touchdown passes Weeden threw with the Cowboys.
Now we know that Oklahoma State is going to continue putting points on the board without them, but will the offense ever be as prolific when the combination is Clint Chelf or Wes Lunt to Tracy Moore? We'll get our first clues this spring.
3. LaMichael James, RB, Oregon
Maybe you think that LaMichael James isn't all that hard to replace given the weapons Oregon has in the backfield. I can see your point, but I can also point out that James nearly doubled Kenjon Barner's rushing total (1,805 yards to 939) in 2011. I mean, this is a man who rushed for 1,805 yards and 18 touchdowns while averaging 7.3 yards per carry in 2011, yet we didn't think it was so amazing based simply on the fact we'd already seen him do similar things in the previous two seasons.
We just got used to it.
Yes, Barner and DeAnthony Thomas are extremely talented backs, but the fact is there's no easy way to replace a back who accounted for 5,888 all-purpose yards and 58 touchdowns in three seasons as a Duck, all at the speed of light.
2. Robert Griffin III, QB, BaylorWill it be harder to fill RG3's shoes, or his socks? Neither will be easy. While we all know how talented Griffin was as a quarterback for Baylor in 2011 and the two seasons before it, it's his impact on the program that will leave the biggest impression. Baylor went from a perennial bottom-feeder in the Big 12 to a team that can call itself the home of a Heisman Trophy winner.
Nick Florence will be the favorite to replace Griffin this spring, but he'll never be able to have the impact on the Baylor program that Griffin did. Instead he'd be much better served to focus on replacing the production on the field. Something that won't be easy, either, but given Art Briles' history with quarterbacks and the way Florence performed in place of Griffin against Texas Tech, it may not be that far-fetched, either.
1. Andrew Luck, QB, Stanford
Andrew Luck didn't win the Heisman Trophy like Robert Griffin did, but that doesn't diminish the impact he had on the Stanford program. In the three seasons before Luck showed up in Palo Alto, Stanford was 10-26, including a 1-11 season in 2006. In Luck's three seasons the Cardinal went 31-8, played in two BCS bowl games and became a national program.
Stanford is essentially the school Notre Dame used to be, and it's all thanks to Luck. Of course, the question now is whether or not Stanford can maintain the success they had under Luck with a new quarterback. Brett Nottingham, Josh Nunes and Robbie Picazo will all enter spring practice looking to replace the most important player in the history of Stanford football, and that's a list that includes John Elway.

Trent Richardson, RB, Alabama. No SEC player was more electrifying to watch on a weekly basis than the Tide workhorse, whose raw strength and unmatched determination could turn an average four-yard gain (usually into the teeth of half the opposing defense) into must-see TV. Of course, the elusive, explosive 70-plus-yard bursts -- like his showstoppers against Ole Miss and Auburn -- weren't too shabby, either. Few have ever combined those gifts like Richardson, and no one in the SEC was any better this season.
Les Miles, LSU. James Franklin has earned legitimate consideration for his work at Vanderbilt. But when you look at not only the juggernaut constructed by Miles in Baton Rouge but his ability in steering it through the storms of the preseason bar fight incident, suspensions, and quarterback controversy, there's not really any other choice to make in this slot.
Tyler Wilson, Jr., Arkansas. It was far from a banner year for quarterbacking in the SEC -- only three teams were even able to keep the same starter for all 12 games -- but you wouldn't know it from watching Wilson, whose 3,422 passing yards led the league by nearly 600 yards. No team in the conference was more dependent on their quarterback, but despite taking frequent poundings behind a suspect line Wilson repaid that faith to the tune of a 10-2 record.
Michael Dyer, Soph., Auburn. The only back besides Richardson to average more than 100 yards per SEC game, Dyer was often the only thing the sputtering Auburn offense had going for it--and he still finished with 1,242 yards while averaging better than 5 yards a carry.
Da'Rick Rogers, Soph., Tennessee. Like Wright, Rogers was supposed to take a back seat to fellow Vol wideout Justin Hunter. But when Hunter went down with an ACL injury in Week 3, Hunter stepped forward to lead the SEC with 1,040 receiving yards and 67 receptions--despite often being the woeful Volunteer offense's only threatening playmaker.
C William Vlachos, Sr., Alabama. The SEC's best center, Vlachos put both his considerable strength and veteran guile to use in leading Alabama to the SEC's most productive rushing attack.
DE Melvin Ingram, Sr, South Carolina. His 13.5 sacks and 8.5 sacks -- both among the SEC's top five totals -- might have been enough anyway. Add in his two defensive touchdowns, critical fake punt touchdown rumble vs. Georgia, and skill at kick-blocking, and he's a total no-brainer.
Jarvis Jones, Soph., Georgia. Todd Grantham's 3-4 system made a star out of Justin Houston a year ago, but it paid even bigger dividends for Jones, who led the SEC in both tackles-for-loss and sacks and his Georgia defense -- one of the nation's best -- in tackles overall.
CB Morris Claiborne, Jr., LSU. As much as we admire Claiborne's 
But since it's no fun not making a guess all the same, we'll offer one here. We've given LSU slight edges
THE LATEST FROM TUSCALOOSA: By this point, there's not a whole lot left for either team to say or report. Saban himself
THE LATEST FROM BATON ROUGE: It's not just the pundits who are saying the two teams are strikingly similar for a game like this: LSU defensive tackle Michael Brockers 

(Maybe the most interesting nugget from Rang's piece? That LSU's Morris Claiborne is "arguably the elite cover corner in the SEC." Wonder what Dre Kirkpatrick, Casey Hayward and even LSU teammate Tyrann Mathieu would say about that.)

20. OLIVER LUCK, athletic director, West Virginia. Luck's influence on college football is two-fold. The first (and most important) has been his effect as the athletic director of West Virginia. Recently, his role as the face of this athletic department has become much more challenging due to the ongoing Bill Stewart/Dana Holgorsen soap opera. In the next few weeks, Luck will have to clean up a he-said/she-said that could end up defining West Virginia football -- and the entire "coach-in-waiting" strategy -- significantly for the near future. If Luck decides that Stewart was trying to convince reporters to dig up dirt on Holgorsen after his hiring in December, he may be faced with the decision of promoting Holgorsen early or -- as some have suggested i- bringing in an entirely new head coach. Somehow, Luck will have to find a way to juggle all of this responsibility while instituting the first year of beer sales at West Virginia athletic events. Despite a negative reaction from many fans, Luck is convinced that the selling beer at the games is going to be the best way to discourage binge drinking before the games and at halftime. It is not entirely uncommon for schools to make this decision, but the logic is often difficult to explain to fans who disapprove of alcohol at college events entirely.
even if it means dropping ticket prices. That means openly promoting celebrating the fact that college football is never going anywhere, never relocating to another city 1,000 miles away, never locking players out and threatening to cancel a season, and never treating fans half as poorly as the NFL is treating its own right now. -- AJ
But unlike other head coaches in charge of troubled programs, there has been no hard evidence to show any kind of cover-up by Davis. When a player's eligibility has been put in question, the school has pulled the player from the active roster and relied on a "next man up" mentality until NCAA clearance. Not only have Davis and athletic director Dick Baddour been cooperative with the NCAA, but North Carolina won their first bowl game since 2001. With no hard evidence yet to surface, Butch Davis continues to avoid the pressures of investigation with ignorance and wins. As long as both factors continue, Davis will be on the sideline in Chapel Hill. -- CP
15. MACK BROWN, head coach, Texas. Since becoming the head coach in Austin in 1998, Brown's teams have gone 133-34, won a national title, and earned two Big 12 championships and six division championships. Brown has won the Bear Bryant Award, Bobby Dodd Coach of the Year Award, and has been the Big 12 coach of the year twice. That's a lot of notches in the belt, but those accolades don't mean much in Austin right now, as a lot of Longhorns fans can't see past 5-7, Texas' record last season. It's hard to believe that a coach who has had as much success at Texas as Brown has could be considered on the hot seat, but if Brown doesn't turn things around this season, he will be.
13. TRENT RICHARDSON, running back, Alabama. There's no polite way to say it, so we'll just say it: the state of Alabama has dominated the sport of college football for the past two years. Each of the last two Heisman Trophies are sitting in Cotton State trophy cases. They just happen to be a stone's throw away from each of the last two BCS championship trophies, also in those same cases. In 2009, Alabama gave us the sport's most complete, dominant defense in years. In 2010, Auburn gave us the sport's most dynamic, polarizing player in years. So what are they going to do for an encore?
2011 will put Kelly's coaching abilities to the test, though, as the Ducks look to finish what they couldn't last season. Oregon has to replace several starters along the offensive and defensive lines but returns starting quarterback Darron Thomas and Heisman Trophy finalist LaMichael James at running back. This will be the first year for the Pac-12 and Kelly would like nothing more than to have his name on the inaugural trophy. His reputation has taken a hit this offseason after allegations regarding payments to Will Lyles for his scouting service, and the head coach would like nothing more than to put those things behind them--with the same quickness with which Kelly attacks everything he does. -- BF
The SEC has been dominating the college football landscape for quite a while now, as the conference has been the home of the last five national champions. So it's not exactly surprising that during the first round of the NFL Draft on Thursday night, more players who called the SEC home during their college career were taken than any other conference.
