TCU, West Virginia and Iowa State weren't expected to do much in the Big 12 this season.

Last weekend's performances might change that perception.

The Horned Frogs, Mountaineers and Cyclones each beat a fellow power conference team on Saturday — and West Virginia and Iowa State did it on the road.

The teams picked 7th, 8th and 9th in the preseason poll respectively had three of the Big 12's four wins over power five teams, showing that the league might be deeper than originally thought.
