Look at these easy lines:
Underdog vs. Purdue and won 82-78.
5 point favorite vs. Tulsa and won 69-44.
Underdog at Kansas St. and won 61-53
4.5 favorite vs. Texas and won 78-63.
3 point faovrite at Texas A&M and won 69-63.
3 point favorite at Oklahoma St. and won 89-81.
3 point favorite at Baylor and won 78-63.
I bet 6 of those games and haven't lost with Oklahoma all year.
