Years are running together on me, but I think this is it.I would’ve guess one of the Wisconsin Final 4 teams or a Michigan/MSU team did it after (this would’ve been 2011?) but maybe this is right. I am not saying I follow this religiously, but I think Michigan and Wisconsin tend to be stronger come tournament time and dont really have big mid season appeal. After I thought about it, it seems that MSU may have been ranked number 1 in 2018
