you realize nobody is arguing he's not a great prospect because he's french, right?
the argument is that he played in a league - which happens to be the french league - that hasn't had a great history of guys hitting in the NBA...AND...that he wasn't that good in that particular league. not one person is arguing he's not a great prospect on the basis that he's french.
it's almost as if you're wanting that to be the argument so you can shoot it down - but at the end of the day all you've done is created a straw man.
