Just the fact that Stevens Point is no longer the presumptive champion of the conference is a sign: the conference is improving and improving fairly rapidly. I don't think it will contend with the popularity of basketball yet--and fortunately, it doesn't have to. Having non-competitive teams in a conference doesn't automatically damn the conference, after all.
Perhaps part of the charm of WIAC is that it can be competitive on several fields or courts. I watch the little scrolling news bar on the ESPN stations and see WIAC schools took DIII titles in volleyball, indoor and outdoor track (men and women) and had very respectable runs in soccer, football and basketball.
Now we need to field teams in lacrosse (game, not city or school), water polo and field hockey.
