K-State was my #26 last week because they hadn't played enough games to quite erase the question mark that came from game 1. At the moment, though, they're one of the couple teams in the driver's seat in the Big 12 and their defense looks legit.
Would have them ranked higher than Iowa State, However, the loss of Skylar Thompson will hurt their path in the future. Still could make a run for the conference championship. 
I'm giving the offense a mulligan for their quarterback injury. Defense looked steady, albeit against a TCU team that can't move the ball between the tackles.
