Did you watch the game? If you did you would have seen that the Gopher players were just trying to run the clock down and not run up the score.

Three-Man Alabama Pulls Off Greatest Loss in NCAA Basketball History
Minnesota cut it pretty close, basically standing around on offensive taking jump shots. Not trying to run up the score is one thing, allowing a team with only three players to cut the lead to 3 pts with 2 min left is kind of dumb.
