From 
Big 12 Sports:
Barnes wins his third Big 12 coaching accolade after leading the Longhorns to a 26-5 regular season record. Despite losing National Player of the Year Kevin Durant from last season's roster, he has had UT in the top five of the rankings for a good part of the year. He led Texas to a share of its second Big 12 crown in the last three years and third overall. The 26 wins for the Longhorns are also the most in regular season competition in school history. Barnes is the first coach to be named Big 12 Coach of the Year three times.
Congrats to Rick Barnes who won Coach of the Year, first teamer DJ Augustin, second teamers Damion James and AJ Abrams.
