I completely agree that Minnesota was the best team in hockey in 1940. However, the AAU title is not indicative of anything. It wasn't even won against college competition, and as a result should not be talked about in comparison with an NCAA Title. The fact that the Gophers hang a banner for it right next to their NCAA Title banners cheapens their NCAA titles. I've said it before, but IMHO if Minnesota wants to hang a banner, hang one for the undefeated season. Had their been an NCAA Tournament in 1940, Minnesota would likely have won it, but it would have been no sure thing. The best team doesn't always win the NCAA Tournament...just ask Brendan Morrison.
That being said, if I were a Gopher fan, I would be very proud of that season. They had great players, won by a lot of lopsided scores, and never lost. I just would care less about hanging a banner for winning the two easiest games of the season.
