With college football season already hitting the halfway point, the contenders have been separating themselves from the pretenders. Week 7 will provide key tests for four unbeaten teams with playoff hopes.
Alabama, which barely hung on to beat Texas A&M last week, takes on No. 6 Tennessee in the biggest game at Knoxville's Neyland Stadium in recent memory. In another top-10 battle of unbeatens, Michigan hosts No. 10 Penn State. In the Big 12, Oklahoma State tangles with TCU, which is fresh off a key win at Kansas, and in the Pac-12, USC faces its toughest challenge so far with a road trip to Utah.
