To weigh in on baseball:
From April through September, I do not give a single fuck about it. The season is way too goddamn long. 162 games is ludicrous. Throw in the 25 or so spring training games and its ungodly long. No sport needs Almost 200 games in order to determine what teams are worthy of making the playoffs. So obviously, I do not have a team I root for since I don't watch.
However, all that changes for the month of October. There is something so incredible about playoff baseball. The intensity can be absolutely incredible, and when its a series like the Yankees vs the Red Sox, you can be guaranteed of some moments you won't forget.
