I think you have a huge unexamined assumption underlying your own argument here, namely, that accurately predicting a bad record helps you feel better when it comes to pass. Guess what, I got more enjoyment out of the 2008 season when I thought the Bills were headed up and had those hopes dashed than I did in the 2009 season when I knew they were going to be terrible. Maybe for some people having that letdown is a bigger deal than it is for others. For me, it's not. I'd rather entertain dreams of playoffs (as ludicrous as it might sound) than preemptively brace for a comeuppance.
