Re: How to get on an international team?
Well, I don't have much to say, but I guess you're aware that european clubs have B teams and Youth teams and that's where they get the players, aside from free agents signings. Ricky Rubio and Gasol weren't drafted there's not a draft for a spanish pro teams, they come from Youth teams and in the case of Rubio, he got himself to the main team real fast...
For that, he really stood out in the B team or Youth teams.
IMO that video idea might work, but I'd say the best you can expect is to get yourself into a Youth team or B team... And consider that this will require you to move to the country of the club. Imagine yourself going to play for Partizan in Belgrade, Serbia... That's a big change for any american.
Try to talk with an agent at least, to have a better idea of what is needed to attract attention from european clubs..
But unless you're a college player, I guess it's not possible to go straight to the senior team, you'll likely have to rise from below to get there.
