I am all-Ohio when it comes to sports, and grew up in north-central Ohio (Mansfield).
College: Do I even need to say anything? I grew up in a sports-minded family, so we watched every Buckeye football and basketball TV broadcast, and listened to the rest on the radio. Only other school(s) I cheer for are Indiana Wesleyan (soccer is king, and we had a pretty good team while I was there) and UCF (hopefully transferring there before too long).
MLB: The Indians. Just like with the Buckeyes, my family was watching any Tribe game that was on TV, and listened to it on the radio if it wasn't. Usually went to at least one or two games every season once Jacob's Field was built (don't think about calling it Progressive Field, fuck that shit). Since moving to NE Indiana, I see and hear more Reds games, and I will enjoy a chance to go to GABP, but I couldn't care less about the Reds. Tribe all the way!
NFL: One of the few major sports my family didn't really pay much attention to, but I grew up with Browns fans, and even though I didn't really understand what it meant, I remember being mad when that asshole packed up and moved the franchise. Then I got really excited when the Browns were revived in Cleveland, and now wallow in agony as we fail to do anything, year after year after year after year after...you get the idea.
NBA: My family has never looked fondly upon the NBA, and I don't much either, but regardless, I knew about the Cavs, but never really followed any one team until I watched His Quitness play in HS and realized what a boost it would be to the Cavs. Sure, call me a bandwagoner for that, but I remain a Cavs fan now, and forever. However I do have fond memories of sitting in our upstairs storage room with a little TV plugged in and watching Jordan and the Bulls pound away at everyone while I would occasionally lose focus and dig through the boxes of stuff we kept up there.
MLS: Never have been much of a real follower, but I do keep an eye on Columbus Crew news and always check their ranking and record in the Ft. Wayne newspaper sports section.
NHL: Again, don't actually do much following, but I do keep an eye on the Blue Jackets and have a small personal celebration when I see they are doing well. I've just never been able to really get into hockey.
Euro Soccer: Yes, I am part of a shameless bandwagon when it comes to the EPL, I pull for Manchester United. I openly admit I'm little more than someone who hopped on the bandwagon, but in reality, I don't honestly care too much. I am much more interested in the US team and their success in the World Cup. International soccer leagues are just a way for me to keep tabs on the top players.
So there you go. Born and raised in Ohio, grew up focused on Ohio sports and nothing will ever change that, no matter where I live in the future.
