Well, we got one epic upset in yesterday's action, with the Butler Bulldogs having knocked off the Pittsburgh Panthers in one of the more unbelievable sequences that you'll ever see to conclude a college basketball game. That loss really managed to mess up a lot of brackets, including those of yours truly, who had the Panthers as part of the national title game (yes, I should have known better).
