(AP) — Western Kentucky coach Jeff Brohm figures his team's best chance at ending No. 19 Marshall's perfect season will come from forcing Thundering Herd quarterback Rakeem Cato to throw. The Thundering Herd's Devon Johnson has 1,573 rushing yards, including 642 in his last three games, and Brohm said Johnson "really is the strength of the team." Cato will try to extend his NCAA record of consecutive games with a TD pass to 44. Doughty leads the Bowl Subdivision with 36 TD passes and will go up against a Marshall defense that hasn't allowed a scoring pass in 14 quarters. Marshall already has clinched a spot in the conference championship game on Dec.
