The Big Ten has at least seven contenders for bids (Indiana, Michigan, Michigan State, Wisconsin, Ohio State, Minnesota, Illinois) and possibly eight (Iowa), depending on your definition of “contenders.” I think that it would take quite a lot for any of the first seven to miss the tourney, at this point.
I’m not sure that I understand what your are trying to accomplish, then.
Illinois and Minnesota are more likely to make the NCAA tournament than Harvard or Princeton (each of which has, in round numbers, a 50% shot), and Illinois and Minnesota also are more likely to win the NCAA tournament than either Harvard or Princeton.
bbonden-The NCAA tells us (i.e, lies) that they aren’t picking teams they think can win, merely who they deem deserving. My main complaint is that the 5 months leading up to conference tourney time is rendered moot for all but the BCS conferences.
