LAST FOUR IN
Colorado Buffaloes (17-11, 7-7 Big 12, RPI: 77, SOS: 73)
Colorado entered Tuesday's projection after their come from behind home win over Texas on Saturday, their fifth over a team ranked in the RPI Top 50 right now, and fourth over a team that's in good shape for a bid, However, Tad Boyle's team is far from safe, as they also have damaging losses to Oklahoma and San Francisco on their profile. Plus, only one of their key wins (Kansas State) came on the road, symptomatic of their 4-9 record away from Boulder.

The Buffaloes need to be careful at Iowa State tonight (Iowa State Sports/ESPN3/Full Court, 8 p.m. ET). The Cyclones all hurt Nebraska's hopes by upsetting the Cornhuskers at Hilton Coliseum on Saturday afternoon. Fittingly, the Buffs host those same Huskers in the final regular season Big 12 game for both teams on Saturday. Nebraska won the first meeting between the two in Lincoln on January 18th, a loss that was the first of four straight (and seven in nine) for Colorado.

LAST FOUR OUT
Oklahoma State Cowboys (18-11, 6-9 Big 12, RPI: 59, SOS: 44)
The Cowboys are yet another team that's all but unstoppable at home, but the complete opposite on the road, as their last two wins away from Stillwater were a pair of December in-state neutral site contests against Tulsa and Alabama. Home victories over fellow bubble residents Kansas State, Baylor, and Missouri State, along with a safe Missouri squad help significantly, but the road struggles and fact this team is destined to finish below .500 in the Big 12 don't. Oklahoma State's only real chance is top Oklahoma Saturday to end on a three-game winning streak and pick up a couple of wins in Kansas City next week.
