TCU was 2-0 versus Kansas State during the regular season. I don't see that pattern changing in their Big 12 Conferernce Tournament game. The Horned Frogs have played better down the stretch even defeating Baylor three games ago. TCU has a chance to draw an NIT bid with a good tournament showing. Kansas State is not going anywhere with a 10-21 record, 3-15 mark in the Big 12. 
The Wildcats actually are a little fat and happy having halted a 10-game losing streak with a 79-63 home win against Iowa State this past Saturday on their senior day. 
TCU is the better and more motivated squad. The Horned Frogs also have revenge incentive. Kansas State defeated them, 70-61, in the Big 12 Tournament last year.
