I reached a point a long time ago in my sports fandom where I can get high with the highs, but I don't get low with the lows. So due to that, I'd much rather be a Leafs fan and get the enjoyment of the regular season, usually some talented players putting up solid numbers, and 1, maybe 2 playoff rounds. That beats the absolute nothingness that comes out of Buffalo from October to May.
A year in emotions of Leafs fans: Optimism -> Excitement -> Nervous Optimism mingled with dread -> Pain and Sadness
A year in emotions of a Sabres fan: Apathy
Give me the rollercoaster.
