In yesterday's gameday thread this was brought up. Not only does it seem that way... as 2632 mentioned, it pretty much is that way.
As you can see, we've only been above .500 on two separate occassions. On both occassions we made sure to plummet back to or below .500, and on three occassions we managed to rattle off a few wins to get to .500 and then realize we are at .500 and immediately divebomb as far from .500 as we can. Yay, go o's.
