Basketball struggles over in Northern Europe as does NFL
Basketball ain't a white sport nor a northern sport, or for that matter even a sport that's played in europe. This isn't about artifically importing a american sport to europe or a europe sport to america like in soccer. It's about bringing a franchise to where the sport already exists.
Hockey is already big in europe more players in the nhl than americans, but can't support it's own league. With no real competition besides soccer, and local mini leagues.
Stockhome, helsinki,Berlin, moscow, prague, and maybe oslo would be a pretty good set up.
