Every single team we've lost to is ranked, most of them in the top 10. With the exception of Bama, we've been competitive and had our chances to win in each of them until the defense let us down (offense against Georgia in the final drives, but we shouldn't have even let Georgia come close to scoring that many points in the first place).
Vandy is the best team we play from here until the end of the season, and even then they aren't even close to the worst team we've lost to (miss st). Barring some horrific circumstances, I just don't see how we don't go 4-0 to finish the season. Anything less is completely unacceptable by both the players and the coaches, as it means they are playing and coaching up and down to the teams they are playing instead of their potential. We'll see how it goes, though.
