For proof, look no further than the number of fouls being called _ or, should we say, not called. Teams were whistled just 17.7 times per game on average, the fewest calls since those numbers were first recorded in 1947-48.

Oklahoma State coach Travis Ford isn’t sure what to expect in the tournament.

“Usually it’s called tighter earlier,” he said. “But that’s something we don’t spend a whole lot of time thinking about, other than we’ve got to adjust. (Those are) things you can’t control. We obviously have no idea who is refereeing our game until right before.”

That’s only appropriate in a tournament where nothing seems certain.
