Something I'll be personally watching in the next year is whether the Big East is actually getting stronger and/ or more even overall. Consider that the conference has a weak bottom - St. John's, Cincy, Rutgers, South Florida, and Providence all had losing records. The Big 12 had 2 teams under .500 (and one @ .500, Mizzou). The Pac 10 had 1 team under .500. The ACC had 2 teams. The SEC had 3 teams (obviously not including Georgia and their run). Even the Atlantic 10 had only 4 teams under .500.
EDIT: I forgot the Big Ten. Living in Big Ten country, I try to. They also had 5 teams under .500. And if you make a quick spreadsheet and mark the percentages of teams that are under .500, they have the most.
