It is interesting to try to guess how many B1G teams will make the NCAA tourney at this point. I believe the top half of the league should make it in the end, that's 7 teams, although 6 may be the more likely total. Joe Lunardi currently has 6 in his latest bracket, but that includes Iowa who is not in the top half (no doubt OSU will be largely responsible for gifting their berth to them if they make it). To listen to the analysts on ESPN, you might think there are only going to be 3 or 4 teams from the league make it with how they keep talking about how Wisconsin is clearly superior to all other teams in the conference & how everybody is mediocre aside from Wisconsin (i.e., "the B1G is down" mantra).
While the league likely will not end up with as many high seeds in the tournament or as many Sweet 16 teams as they have had lately, there are a handful of teams in the conference that are shaping up to be tourney caliber. The past few years have been ones where the league was historically strong at the top in terms of number of teams advancing to the Sweet 16. 2012-14 were really strong years for the league, but this year it's really not like it's Wisconsin and then a bunch of crap teams as the media tries to make it out to be. The B1G schedule makers did their best to further the Wisconsin supremacy perception by giving them the minimum 6 games against the top half of the league, in other words the Badgers have 2/3 of their league games against the weakest half of the conference (and no one else in the top half had the same degree of soft schedule), so it's facilitated the continuation of the perception that they're by far the best team in the league even though they lost to Rutgers and barely beat a UM team w/o LeVert (which may be their best conference win). I just don't buy that Wisconsin is a lot better than everybody else in the B1G. The nonconference performance of the conference was generally lackluster, but I would call this year more of an average season for the B1G as opposed to a poor one, it just looks poor in comparison to the historically strong seasons that preceeded it.
