Liberty plays extremely slow, but is very efficient offensively. The Flames could frustrate Oklahoma State. But I don't believe that will happen. The Cowboys are hot, played a far more difficult schedule and feature superstar guard Cade Cunningham. That combination should enable them to cover this mid-range number.
Oklahoma State emerged as a Big 12 Conference power knocking off No. 2 Baylor in the conference semifinals before falling to Texas, 91-86, in the conference tourney title game. That loss may actually help the Cowboys because they won't be taking Liberty lightly after defeating six ranked teams this month. Oklahoma State has covered seven of the eight times it has met a foe with a winning percentage above .600. 
The Flames earned their way to the NCAA Tournament by capturing the Atlantic Sun Conference Tournament. I regard the Atlantic Sun as a bottom-five conference. One of Liberty's non-league victories came against Lancaster Bible, 90-49. So that padded the Flames' season statistics. When Liberty went up against NCAA Tournament teams Missouri and Purdue earlier in the season they lost by 9 and 13 points.
