I used to watch lot of european basketball before (I'm european). If I have to choose the best country to pick up a nba prospect, that would be Italy. The basketball culture there is based on 2 main skills (toughness and accuracy at shooting), they excel at those 2 compare to other countries.
I believe it is easier to adapt an Italian to the nba.
But again, it's a general rule, I don't know this guy particularly.
I think with the new CBA rules, franchise will have to find opportunities in other countries to fill up their roster at low cost. A good pick and you can save a couple of millions for the same results.
