When Mizzou runs

Mizzou's running game showed some progress against Colorado, whose run defense ranks 10th in the Big 12, and Baylor's run defense is ranked last. With two runners in the backfield more often, De'Vion Moore is getting more opportunities. He averaged 7.2 yards a carry against Colorado. Mizzou's backs carried the ball a season-high 37 times against Colorado.

When Mizzou passes

With Blaine Gabbert looking like he's back to health and able to push off his back foot, Mizzou's passing game becomes potent again. Baylor does have a solid pass defense — it trails only Nebraska, Texas and Oklahoma in the Big 12 — and linebacker Joe Pawelek is someone to watch out for. His 388 career tackles are the most of any active player, and he has nine career interceptions. He was seventh in the nation last season in tackles and is second in the Big 12 this season with 9.4 a game.

When Baylor runs

Had quarterback Robert Griffin, a dual-threat player and one of the most dangerous offensive players in the league, not torn a knee ligament in the Bears' third game, their running game would be a potent part of their attack. Now, not so much. In its past four games, Baylor has run for 192 yards, total. Leading running back Jay Finley averages 52.2 yards a game.

When Baylor passes

Griffin's replacement, Blake Szymanski, has been out with an injured shoulder, leaving the job to freshman Nick Florence, who has an efficiency rating of 110.0, which puts him 11th in the league. He ranks near the bottom of the league in almost every category. In the past four games, Baylor has three offensive touchdowns, and two of them have come in the fourth quarter after the outcome was long since decided.
