There has only been one year where we deserved to get in on the bubble - 2007. 29 of 30 people had us in on the final bracket matrix -- I did not have us as a clear in, but safely in nonetheless. I don't think 2007 was any vendetta but just a case of poor logic. If you remember we last at home to Drexel that year -- and Drexel was also a team that many thought would get in -- (16 of 30 on the matrix). My guess is that when they tried to separate the bubble, they decided Drexel was out, and then used the if A beat B, and A is not in, then B cannot be in either logic. Just my guess.

And if you believe John Feinstein (per something Alsacs said a few days ago) we were the last team out in 2008 after Georgia won the SEC which was a heck of a generous placement for us (we did not deserve that spot at all). Of course it is just heresay, but that does not indicate a vendetta if it was true. In 2008, 2 out of 53 people had us in the tourney per the final matrix -- so it would have been quite generous.
