This is a good conversation so don't let me interrupt too much...I've never bought a jersey for any sport, but I want to buy the throwback jersey cutler sported last night. I have a few questions if someone wouldn't mind. Where is the best place to buy one of these? Do you buy the authentic jerseys or the replicas? If I wear an XL t-shirt should I get an XL jersey, or do jersey sizes run a size larger?
