Every year there are stars buried on the depth chart. They are waiting in the wings like hungry sharks for their chance to get on the field and show everyone what they can do.
For the most part, these players aren't known well nationally, but in-house it's a different story. Their coaches and fans know exactly what these players can do, but its simply a matter of waiting their turn.
These players are backups behind veterans who've proven themselves worthy of a starting spot.
But a backup can become a star overnight if the circumstances are right.
Of course, no one wants to see someone get injured, but it happens and that's often the best way for an unknown or a little-known to step on the field and flourish.
That's part of the game.
So who are the stars masquerading as backups this year?
Who's an injury away from blowing up?
Lynn was one of the highest-rated cornerbacks of the 2009 college football recruiting class, ranked No. 1 by Scouts and No. 8 by Rivals at his position.
He's got all the intangibles to be an elite cover corner and right now is just waiting his turn at Oklahoma behind Demontre Hurst and Jonathan Nelson.
He spent last season in a redshirt, learning the defense and bulking up.
If either of the names ahead of him start slipping up or go down with an injury, Lynn can step in immediately and be a force on the outside. If he did, it would be surprising to see him ever give up a starting spot once it's his.
When Roy Helu Jr. injured his knee last season in the Holiday Bowl, Burkhead stepped in and delivered with 17 carries for 89 yards and touchdown.
What's even more impressive is that he was so comfortable in the Wildcat offense. It would be very surprising to see him not retain significant minutes this season even with Helu back.
Now if something were to happen to Helu this season, Burkhead would assume complete control of the backfield and is just waiting to breakout.
Fellows was a five star defensive end coming out of Garfield Heights high school in 2009, but redshirted last season to fine-tune his technique and add some bulk to his frame.
The other reason he redshirted was Cameron Heyward, Ohio State's star defensive end who is one of the best playmakers in the country.
Fellows is a powerful bull-rusher who was a bit raw a year ago, but looks ready to do big things when he gets the chance.
That chance would come the moment anything happened to Heyward.
Baxter hasn't even played a college football game yet, but this is one 2010 recruit that has the chance to be one of the biggest instant impact freshman in the country.
Regardless of how the situation plays out, he's going to be a big part of USC's game plan. Allen Bradford is expected to get the majority of the carries in Lane Kiffen's new offense.
Now if Bradford were to have an injury, Baxter could be in line to reproduce the type of production Ryan Williams and Dion Lewis reached for Virginia Tech and Pitt as freshman a year ago.
LSU's secondary is about as deep as anyone's in the country, which is the main reason 2009's No. 1 high school safety hasn't made much of an impact yet, besides a solid performance in the spring.
He's behind Jai Eugene on the depth chart, but this is a situation where an injury to not only Eugene, but even Patrick Peterson or Morris Claiborne could totally shift the dynamic of the defense and force Les Miles to move some pieces around.
If anyone's going to get elevated to the starting unit as a result, it'll be Loston first and foremost; and he's more than ready for the chance.
Shanahan had a solid end to the 2009 season with a five-catch, 83-yard performance in the Meineke Car Care Bowl. Considering he only had 10 catches on the year before then, that stands to be a possible breakout performance.
The depth chart thinned out over the summer at receiver and Pitt is looking for a new No. 2 wideout. Shanahan should be in the driver's seat to start opposite Jonathan Baldwin in 2010.
That doesn't technically make him a backup, but he's not a No. 1.
If Baldwin suffers an injury, the passing game would go almost entirely through Shanahan. Based on what he's shown in spurts, that could mean big things.
Ryan Clarke did a solid job as the Mountaineers' fullback last season, but this big-bodied rusher is more than just a blocker or a short-yardage eater.
When he gets the chance to run, Clarke has shown flashes of brilliance and a powerful north-south running style. There isn't a huge sample of carries to go by, but the talent is there and he should be a bigger part of the offense in 2010.
With Neol Devine returning for his senior year, Clarke will take a backseat.
That's unless something happens to Devine.
Shepard was the crown jewel of LSU's 2009 recruiting class and the second-rated passer in the country behind Matt Barkley of USC. He's got elite athleticism and speed and is the type of playmaker that can score at any given moment.
Les Miles has already talked about using him in a multitude of ways next season, getting him involved in the offense anyway possible. That means time at receiver and H-Back, but the true hurdle for Shepard is Jordan Jefferson, the starting quarterback.
Some argue that Sheppard should already be the starter, but Miles has balked at such a commitment to this point. An injury to to Jefferson would alleviate the stress of that situation and get LSU's best playmaker where he belongs.
The Longhorns might have lost Sergio Kindle and Roddrick Muckelro, but they have a stable of talented linebackers headlined by Emmanuel Acho, Keenan Robinson, and Dustan Earnest.
They also got a huge haul of new recruits this year. It begins with Jordan Hicks, the five star outside linebacker from Lakota West high school that was rated as one of the top players in the country.
He'll make an impact as a true freshman, but a key injury could get him into the starting lineup. That's where he could really blow up.
By now everyone knows who Trent Richardson is. Even though he plays behind Heisman Trophy winner Mark Ingram at Alabama, he's still considered one of the top running backs in the nation.
He'll get a lot more carries in 2010 and should be a huge part of the offense. Some people in the Crimson Tide camp think he's the best rusher on campus and if something were to happen to Ingram, Richardson would get the lion's share in the backfield.
Give him that and he might prove to be the best rusher in the college game.
