MLB = Reds
Minor League Baseball = Mud Hens
The unexpected by-product of living in the Toledo area and following the Mud Hens has been a growing affection for the Detroit TiIgers also. So far neither the Reds or Tigers are really much of a threat to each other so my interests are not conflicting to this point, but my loyalty will always be with the Reds should such a decision have to be made at some point.
NCAA Football and basketball = Ohio State, I'm an Ohio boy and an alum to boot. Actually a bigger hoops fan than football even. Kept the shot chart for Gary Williams for 2 years when I was in school. I also root for the local MAC teams (Bowling Green and Toledo), and appreciate good college basketball in general. Started following Maryland even more closely when Williams went there from tOSU.
NFL - used to be the Browns, and I knew the roster as well as any team I ever followed. Then the move (of the team), I got married , had daughter and house etc and no time left to follow and no NFL passion left to drive me. So this is just for entertainment purposes only -though I like to follow ex-Buckeyes...
NBA - no real passionate favorites, but am following the Bucks closer than anyone else due to Michael Redd (also like TJ Ford and Bogut). May develop a stronger following eventually if the roster remains a bit static.
