KANSAS CITY, Mo. — Colorado managed just three wins in the entire Big 12 regular-season slate.Now the 16th-seeded Buffaloes are riding a two-game winning streak as they prepare to face eighth-seeded West Virginia in the second round of the conference tournament on Wednesday.Colorado (13-19) opened tournament play with a 69-67 win on Tuesday against TCU — the same team the Buffaloes beat 76-56 on Saturday in Boulder, Colo. Now the Buffaloes will have to defeat the Mountaineers to keep their season alive.On Tuesday, the Buffaloes opened the second half on a 14-1 run to grab a 40-28 lead after less than five minutes. Colorado managed to maintain the advantage the rest of the way, although TCU made it a one-possession game in the final minute.Andrej Jakimovski led Colorado with 18 points, and Julian Hammond III scored 16.”I would say that when you don’t play your best — and we were far from our best today — and you figure out how to win a game in March, it says something about your guys,” Buffaloes coach Tad Boyle said postgame.”This team has come a long way. We’ve been through a lot together and they’ve stuck together, and to see them with the fight today, even though we didn’t play our best, (is impressive). I mean, you give up 22 offensive rebounds, you turn it over 15 times and you win, it’s kind of a head-scratcher.”
