Series Record: Western Michigan leads 23-19.
WHAT'S AT STAKE
The unbeaten Broncos are trying to play their way into a BCS bowl bid and a stumble anywhere along the way would end that dream. Ball State, meanwhile, is trying to pull itself out of the West Division basement with what would be the biggest upset of the MAC season.
Jarvion Franklin vs. Ball State defense. Franklin entered the weekend as the MAC's No. 2 rusher, with averages of 113.6 yards per game and 5.8 yards per carry. If Ball State wants to make this game competitive, the run defense must play better than its No. 7 conference ranking (153.2 yards rushing allowed per game).
PLAYERS TO WATCH
Western Michigan: Franklin. The 6-foot, 228-pound running back has a chance to showcase his old-school, bulldozing style on national television. And he isn't shy about why he likes running over defenders - calling it the quickest way to get first downs.
Ball State: RB James Gilbert. The sophomore, who first committed to Western Michigan before signing with Ball State, actually started the weekend as the MAC's leading rusher with 987 yards and 11 TDs. The Cardinals need him to be just as effective against Western Michigan's stout defense to keep the score close, the clock running and the Broncos' offense off the field.
