One big difference between college and pro football is player personnel turnover. In college football, seniors graduate, and some juniors and even sophomores leave early. Even some freshman transfer due to personal reasons or lack of playing time.
That is why recruiting and developing young talent play such huge roles in college football. If a coaching staff isn't careful, they can be in a world of hurt once the seniors and juniors leave. One or two poor recruiting classes can be trouble for a team's upcoming season.
Let's take a look at five teams that could be on the verge of disaster if one key injury happens during the 2010 season.
Obviously Jake Locker didn't heed the warnings of potential disaster while watching Sam Bradford's senior season come to a premature end.
Locker decided to return U-Dub for one more season to the delight of Coach Sarkisian, but what happens if Locker goes down?
Behind No. 10 is redshirt freshman Keith Price and true freshman Nick Montana, and that is it.
Keep your fingers crossed, Husky Nation.
Yes, Timmy is gone, and now the keys belong to QB John Brantley. However, if Brantley were to go down, how would the Gators do without him?
Trey Burton, a true freshman from Venice Senior High School in Venice, Fla. would be behind center. Coach Urban Meyer has also been flirting with redshirt freshman TE Jordan Reed for Wildcat formations.
Are you kidding me? Burton shows promise, but to rely on him for the 2010 season if Brantley were to be lost would doom the Gators' season.
UCLA fans are impressed with Kevin Prince, a QB with mobility and a strong arm. However, he has battled injuries during his career, and another in 2010 could spell trouble for the Bruins.
Waiting in the wings, just in case, are Richard Brehaut, a sophomore from Alta Loma, Clayton Tunney, a UC Davis transfer, Nick Crissman, a redshirt sophomore from Surfside, CA, and Ted Landers, a redshirt freshman from Torrance.
Very little experience is what awaits if Prince goes down.
After a very successful freshman season, RB Dion Lewis is expected to carry the load for the Panthers in 2010.
Behind him is a group of talented, but inexperienced players: Kevin Adams, Jason Douglas, Chris Burns, and Ray Graham.
Coach Dave Wannstedt must bring this RB corps around quickly, if for any other reason to strengthen and support Lewis in 2010.
New head coach Derrick Dooley has inexperience to deal with at the QB position this season. Matt Simms, son of former NY Giants' QB Phil Simms and brother of former Texas QB Chris Simms, has transferred to Tennessee via Junior College.
Competing for the starting position is another JuCo transfer, Nick Lamaison, and true freshmen Tyler Bray and Mike Fromke.
One sack could turn the 2010 season into a nightmare for the Volunteers.
