I find the older I get, the less fanatical I am. Don't get me wrong, I'm still a die hard bills fan. Instill feel the emotion after a crushing loss or a huge win. However, I don't get all worked up about what's being said in training camp anymore. "so and so looks great, this guy stinks" etc. I fully expect over reaction once the pre season games start, but I've just learned not to let the small stuff bother me anymore.
No matter what though, I'm always hyped for the bills season. Even in some of the worst seasons (ie 2010) I will watch every game start to finish
