The 2013 Mizzou team was undefeated going into the NCAA tournament. Many of their fans thought they had the national championship locked up. I told them they would lose in the 2nd round to a middle of the pack B1G team. They lost in the 2nd round to Purdue, who finished 7th in the B1G.
I told Pitt fans this year they would lose to a middle of the pack B1G team. They lost in the second round to Michigan, who finished 7th in the B1G.
Teams from weak conferences like the ACC and SEC do themselves no favors by scheduling weak non-conference opponents, but they do it every year and get a rude awakening in the NCAA tournament.
