Oklahoma State's resume doesn't get enough love in my opinion. They have a very good win against Baylor, and wins at Texas and vs. Kansas State are also very solid. They did lose at Iowa State, but they still have a solid resume.
Oklahoma State played their best game of the season and were so dominant against Kansas that they put the backup QB in mid-2nd quarter.  Tied for 2nd in the Big 12 and the Cowboys have one of the country's best defenses.
a and m's win is just too good, basically their year all depends on Bedlam, which is always worrying (rooting for you tho, and the likely rematch in the b12 game)
