With some teams the loss of one player could have a significant impact in how their team's fortunes turn out this season. If this compilation was being made before games were played last week, Aaron Murray and Trent Richardson would have topped the list.
What a difference a week of games makes.
So, who are these key players? Here is a quick list.
Brandon Bolden, RB, Ole Miss
Against BYU the Rebels found out what life is like without the powerful running back. After just four carries Saturday Bolden went to the sidelines for the balance of the Ole Miss loss to the Cougars.
The Rebel offense failed to score a single touchdown. There is concern Bolden may miss several games as a result of his injured ankle.
Brandon Boykin, DB, Georgia
Boykin may be listed as a DB, but against Boise State his 80-yard rushing touchdown accounted for all but 50 of Georgia's rushing yards for the game. Boykin is an excellent kick returner and averaged 22 yards for his five returns in the game. Oh, as a DB his also pretty salty.
Stephen Garcia, QB, South Carolina
There must be a reason Steve Spurrier has not kicked Garcia off the Gamecock football team. It might have been on display when Garcia came off the bench Saturday night to lead South Carolina back from a 17-0 deficit to a nineteen point win over East Carolina Saturday night.
For the night, Garcia ran for two touchdowns and tossed one.
Trent Richardson, RB, Alabama
Richardson was the Tide's third leading rusher against Kent State, but make no mistake, this Alabama football will team will go on offense only as far as his legs carry them.
Against Kent State he was not needed to carry the load, but look for more from Richardson against Penn State this Saturday.
Tyler Bray, QB, Tennessee
Saturday night Bray tossed three TD passes while completing seventeen of his twenty four pass attempts for 293 yards. Last year Bray went 4-1 starting for the Vols, and his gun slingers mentality will be tempered this season with a touch of maturity.
