I dont think he has.
True in college football 37 yards for one game is not good, however look at Daren's other two games. 221 and 292. His total even with the horrible game his 550 yards. Cedrick is 558, so Ced is not that far and beyond Daren this year. Also look at some other stats. In all time Big 12 rushing leaders Daren is second all time behind your beloved Ricky, and if he has the same season he had last year he will pass him. I promise you that if he becomes the all time big 12 rushing leader he is a much bigger heisman hopefull than Cedric.
