Those two things really are what I think of when I think of professional sports in general. I have friends that are fans of good teams and bad teams and the one thing you can tell is the difference in how they react to a win/loss. The bad team fans(complacent team) a win is something that is really exciting. A loss is basically just another day/game. A good team fan gets upset over a loss and is excited too, but doesn't hang on to it the same way.
I'm tired of being excited over wins and hanging on to them (unless they are playoff games).
Another way of thinking of it. Ask a pats fan who they lost to last season then ask a bills fan who they won against?
Most true fans will get most of them right.
