I know what you're saying (and I agree), but they lost to Nebraska in the final regular season game of the year when they were playing for a potential 1 seed and got utterly dominated by a team that has essentially 0 basketball prominence or talent. You could say it didn't matter to them or that Nebraska played above their level or whatever, but there was also a lot on the line for Wisconsin. Either way, I'm stoked for the game and it'll be a great one (I'll more than likely be there =D).
Just to clarify, I'm from Nebraska and I've followed the team my entire life. It's amazing what Tim Miles has done for the program, but I don't think they're at some even semi-elite level yet where they can win against good teams consistently (see losing in the first round of the conference tourney and NCAA tourney). They absolutely played way beyond their level in that game, but they also showed how you can shut down Wisconsin.
That Nebraska game was at home and it was a game that would get them into the NCAA tourney. You are making too much of it. There was nothing on the line for Wisconsin that game. They had the two seed locked up.
