I’ll get right to the gist of the matter.
At the risk of sounding like a broken record and mentioning what everyone knows already, Professional Sports and playing for a National Team just doesn’t work. For example: As if to emphasize my point, fresh this morning as I wrote this, Yahoo reports that the Dallas Mavericks is not allowing Dirk Nowitzki to play for the Euro League. Notwithstanding both parties’ cordial reaction re the matter, the fact still remains a player’s two loyalties, playing for country whilst making a living playing as a pro is akin to having cake and attempting to eat it too.
You can’t make a living as a pro and then drop everything to play for free for the National Team and expect everyone (ie. your bosses) to be happy about it. You just can’t.
