Well, the funny thing about the Big 10 is, 4 teams are above .500, and every remaining team in the conference (10 to be exact) have exactly 2 wins. They range from 2-2 to 2-5.
The top 4 teams have 4 losses between them. I don't see any real meaning to it, but just odd statistically...
Also, every other P5 conference has at least 5 teams over .500
