Loved the D against KU for most of the game. Really just liked how hard OU played. If OU plays that hard, they will be fine against UT. OU's best D might be transition offense. Not many teams, sans KU, want to run with OU. If OU forces the tempo, UT may try to slow down and then our D in the half-court with the hard trap and aggressive play in the passing lanes becomes more effective.
Outside of D, it's rebounding and shooting a good percentage from 3. This is the same formula for every game - in my opinion - for this team.
In Big 12 play OU has shot 42% from three in wins compared to shooting 30% in losses.
