The UK game in 2011 was maybe the worst I've ever felt after a win. Joker was clearly not the answer. Yet somehow we won with a WR playing QB. Yes, it was nice to break the streak, but I always wish we broke it in one of the years where we were actually decent under Brooks. But that's the irony of UK football it seems.
Worst ever after a loss, in basketball actually, was Wisconsin 2014. Clearly the best team imo, and only a few teams could take us. Unfortunately we didn't show up for the big stage, ran into a great team, and the players (Cal coached poorly too) struggled.
