I'm a big fan of collecting older sports memoribilia, I have a really old Hawks jersey made by Starter, probably from the late 80s that I still rock around the house (Sleeves are a bit short, this thing must have been huge on me as a kid)
Also have a Dallas Stars jersey, Mike Modano was my favorite hockey player growing up. All of my ice skates and rollerblades had #9 on it, every time I've ever been in a rollerhockey league I've worn #9. He was my guy. I was sad to see him in Detroit, but don't even remember that part of his career. Guy was phenomenal.
Few other randoms I have, Wayne Gretzky Edmonton Oilers, Super Mario OLLLLD Penguins, a Havlat Hawks jersey, Carbomb Hawks jersey, and a Brent Sopel jersey (I met him and even had it autographed have pics somewhere) haha!
I typically like to wear obscure players and jerseys that most people never see around...
