Three of the top 4 games involved Big 10 schools. Probably part of the reason they seem to get more of their teams into the tourney. Helps TV ratings.
After watching a replay of the game twice now, I have concluded;
Michigan wanted it more.
UT was intimidated and choked down the stretch.
Biggest cliché in sports may be “team A wanted it more”. Occasionally there is a team thats distracted due to some outside influences such as their coach being fired. But for the overwhelming majority of teams, especially those playing in March Madness, all very much want to win and are bringing what they view as their best efforts. Just because you were out scored doesn’t mean you were out desired.
