Patterson had strung together some great seasons prior to join the Big 12. 13-0 in '10; 12-1 in '09; 11-2 in '08; '06 and '03; 11-1 in '05; and 10-2 in '02. Definitely not comparable.
I've watched TCUs Boykin go from a FR gunslinger thrown into action his 1st yr, to part time RB/QB/WR his 2nd, to a great QB his 3rd. Talented yes, but big diff with new OCs.
