I just think travel would be a mess. I'm not familiar with the time zones over there, but wouldn't teams get completely messed up by that?
I mean just using a quick glance it's 1:24 right now in New York... 6:24 p.m. in London. So would a team always need a day off before heading over to Europe to play their game.
I think it could work with the NFL schedule because obviously you have the whole week, but the NBA where you're essentially in a different city every day, that would just be a mess.
Also, I can't imagine too many players would be excited about playing in Israel or whatever, even if it is the NBA. You get guys that are reluctant to even go to Toronto, let alone Europe.
