The most popular jersey in the state of Ohio are Cleveland Browns jerseys, according to jersey sales at Dick's Sporting Good stores -- which doesn't include the Devon Still jersey deal with the Cincinnati Bengals and Children's Hospital (those have to be bought at the team's Pro Shop). Maybe that's not completely shocking (the whole Johnny Manziel thing). The Cincinnati Bengals, at least, have Kentucky.
Though, in response to this Yahoo! Sports article, Cincinnati is no more in Kentucky than Cleveland is in Lake Erie (and there's probably a lot of Browns jersey in there too!).
When you go to a Bengals game, which jersey are you wearing?
