Big 12 Game Balls: Week 7 October, 16, 2012 @ 3:45 By David Ubben | ESPN.com James Sims, RB, Kansas: Sims seems to have become a fixture here. Kansas hasn't won much this year, but Sims has been outstanding since returning from a three-game suspension. Coach Charlie Weis called him a workhorse last week, and he proved it on Saturday, rushing 27 times for 138 yards and a touchdown. He also caught three passes for 42 yards and carried the load for a KU rushing offense missing back Tony Pierson.
