The Buffaloes trailed 27-10 more than 13 minutes into the game before taking their first lead with just under 10 minutes remaining in the contest.”We turned that thing over like it was nobody’s business and then started feeling sorry for ourselves,” said Colorado’s Tad Boyle, who is one win away from 300 as Buffaloes head coach. “… Our guys finally woke up defensively. We got some stops, strung some stuff together and got out in transition.”Colorado had 18 turnovers, with 13 of those coming in the first half, and finished with a 45-28 rebounding advantage. The Buffaloes took control with a 19-2 run in the second half.Colorado still has a trip to the Maui Invitational ahead as the program gets set for its return to the Big 12 Conference on Dec. 30.”We’re going to watch a lot of film,” said Boyle, a former Northern Colorado head coach who was inducted into the school’s sports hall of fame in August. “There’s a lot of improvements to be made.”
