Outside of the fact that the Big East has a truly elite program in Villanova, their only real strength is depth. They don't have the pushovers at the bottom that most mid-majors have, but let's take a look at their bottom 5, and compare it to the Big XII (since they're similarly structured conferences).
Seton Hall, St Johns, Butler, Providence, DePaul.
Texas, Oklahoma, TCU, OSU, WVU.
It's not even close. The Big East is the midmajor version of the Big XII. This has been a ho-hum year by OU standards, but I believe we'd have finished second in the Big East, and you'd be really hard-pressed to make an argument we'd have ended up below 3.
