I have thought for a long time, that the big ten does not fit the Tourney well. I know MSU has killed it and Wisconsin has recently, but overall, it seems to me, that the style of play and the officiating "prepares" the B1G to not fit well in the tourney. Many on this board think CMP has not adapted to the new style of play - I'm not sure many other teams in the B1G have adapted a lot more, and there are the new rules that hamper defenses, or so they say, although defense has changed the ending of a lot of games in the tourney. Anyway, there is a lot of playground balling going on in other parts of the country. The B1G tends to recruit in the midwest. Great basketball players, but not playground ballers. The B1G has overall been a bit staid, and the officiating has been horrible. When you come off of 18 games of B1G officiating and get other officials in the tourney plus running into a great zone defense, or running into some playground ballers who are allowed to run crazy on the court... it alters things.
With all that said, yes, the B1G was down this year.
