Reality is that Miami was better than us on Senior Day, 1999. We were lucky to win in overtime at their place, and they beat us at ours, as we had to rally back from 10 down late to tie it. Pitt probably looked better than us at this time in 2004. And almost everyone looked better than us right about now in 2011.
Kentucky's two most dominant national championship teams in my lifetime looked terrible in the SEC title game - Mississippi State in 1996 and Vandy a couple years ago.
I wouldn't bet on banner four happening, championships are hard, but you can't take one loss in one sliver of time to one specific team and throw in the towel.
