David and Kevin discuss the biggest games to come in Week 4 of the CFB season, including what is "on the line" for Utah when they come out west to play USC (1:45) and is it fair to wonder about Michigan's identity ahead of their Top 25 showdown with Wisconsin (5:57)? Plus, notes on Auburn-Texas A&M (10:37), Notre Dame-Georgia (17:06), Tennessee-Florida (20:12) and Oklahoma State-Texas (26:38).
