The Tide actually outscored Minnesota 30-22 over the course of the last 10+ minutes while playing 3-on-5. And Minnesota is the #14 team in the country right now!
Minn could have easily run it up. Pitino took the foot off on purpose. He, likely, after seeing that the game was in hand with the 2 man advantage, didn't want to add fuel to the fire. Class move in my book. Tempers flare in sports - it happens. There was nothing to be gained by exploiting the circumstances and winning by 40, or drawing fouls to leave fewer of 'Bama's players on the floor, etc.
