Ohio State Alumnus....no further explanation needed there.
I grew up a hockey player and played into college, so hockey is my pure professional sport affiliation. Back in the day, Madison Square Garden Network and USA were the cable TV sources for the NHL. The Islanders were in the 2nd season of their cup run and I was the biggest Mike Bossy fan ever. Eventually, I started to gravitate towards rangers and their original six heritage. They were hardly the juggernaut the Isles were but it felt right to give them my allegiance. That has never changed. That is the one instances in my life where I changed my allegiance.
I enjoy pro football, baseball and basketball but it is as a fan of the game and not of any team in particular. As much as I enjoy the sports themselves, the BS associated with the big professional sports drives me further away from them each year.
Other than the Buckeyes and NY Rangers, I have no allegiances that I am emotionally invested in. But I must admit, living in Ann Arbor I invest quite a bit of subliminal energy into wishing nothing bad things for the University of Michigan football program, that shit stain helmet (thanks Ramzy) and their arrogant, delusional, suck ass fans.
