Illinois has been much more efficient in their games defensively, and while Michigan has been more efficient offensively, Illinois has still been efficient on both ends of the court. In terms of predictive value and discussion on how good a team really is, things like offensive and defensive efficiency matter a lot more than who a team has beaten. Also, the team Illinois lost to, Clemson, rates really, really high right now (about as high as Duke, higher than UCLA and much higher than Maryland). Michigan is already in the "also receiving votes" category in both polls, which is right about where they should be. Illinois and Northwestern are just barely starting to get vote consideration in the polls, which is why I think they should be a bit higher. Ohio State and Purdue are really the only top 25 teams right now in the Big Ten, but really, Illinois is right there on the cusp statistically, which is as surprising to me as anything, really. There are maybe 6 Big Ten teams between 26 and 50 right now (Illinois, MSU, Northwestern, Michigan, Wisconsin, Iowa), although Wisconsin and Iowa are borderline. If the teams all play according to plan, with no upsets, which would match the standings I posted a couple pages back, there'd be a decent argument for 7 teams from the conference in the tourney. Only 4 are really getting consideration right now (MSU, Purdue, Wisconsin, OSU), but Michigan is probably getting the most pub of the rest.
