There is a real possibility everyone can be 1-1 in league play by the end of the week. Or the very least everyone will be 1-1 except Baylor (2-0) and Texas Tech (0-2) Then with a win against Baylor on Tuesday we sitting back in 1st place. 
Games Saturday:
Texas Tech vs. Baylor
Kansas State vs. Missouri
Oklahoma vs. Kansas
Texas A&M vs. Iowa State
Texas vs. Oklahoma State
I'm on record of not loving KU's squad this year and tonight doesn't change that at all, but comeonman they aren't losing to OU.
I don't think it will happen, either, but OU is much better than they have been the last few years, and this KU team seems somewhat susceptible to a letdown, especially on the road. I'd say OU has about a 20% chance.
