Carlyle Holliday - He did get injured during a run, and Pat Dillingham had to finish the game, with bad results.
Brady Quinn - Right guy, wrong coach
As the others have stated, it appears you were referring to Jarious Jackson, who was supposed to take an intentional safety at the end of the LSU game. It was a true screwup, and one that cost us the USC game (and a Bowl Coalition game berth). Even though he was playing in the Gator Bowl, he was so hesitant during the first three quarters that we had already lost the game by then.
