the following is a list of in-arguable facts:
B1G underperformed expectations only slightly in the tourney so far, losing 3 games as favorites (rutgers, iowa (LOL) and wisc (LOL!))
conversely, B1G has won just a single game as an underdog - michigan (b1g's best tourney team historically) knocked off tenn, bringing Rick Barnes's tourney record against the spread to an astonishing 2-12-1. in other words, there wasn't a more predictable upset all tournament.
I and several others expected just 2 (or less) of B1G's 9 teams to make it past the first weekend. Vegas agreed - favoring just 2 B1G teams in their round of 32 matchups (purdue/wisc).
bottom line - if you view the B1G as anything other than an average (at best) power hoops conference, that's on you. there haven't really been any surprises so far for those of us who view the conference accurately when compared to its peers.
