There's no better example of the Big 12's depth and talent than TCU. The Horned Frogs entered league play at 12-0 -- and promptly lost four of their first five games. Of course, those five games were no cakewalk: vs. Oklahoma, at Baylor, vs. Kansas, at Texas, at Oklahoma.
The scary part about the Big 12? That five-game stretch isn't really an anomaly. That's the way the league is this season. The worst team is Iowa State -- which has beaten top-50-caliber teams Baylor and Boise State by double digits. The other 1-4 team, in addition to TCU and Iowa State, is Baylor, which entered Big 12 play in the Top 25 after beating Creighton and Wisconsin.
