First of all, sounds like you had an awesome career. Fantastic!
Second, I don't really agree with you about the more all-round thing, judging solely from the Euro players in the NBA. Big guys cannot really handle the ball very well, at least not any better than their US counterparts.
All the European centers I can think of playing right now are
Diaw Mahinmi Krstic Milicic Biedrins Petro Turiaf Pachulia Koufos Big Z Pecovic Elson Gadzuric
None of them strike me as great ball handlers or able to play forward very well, except for Diaw. Maybe they do and can in the European leagues because the defense is not as strong. I don't know. But I disagree with people who make the point about European players being more well-rounded or having more basketball smarts. I think what they are seeing is that European basketball is much much slower than American basketball and much less creative. I'm not trying to bag on European hoops. I loved playing there- pickup and organized- and I think Sabonis is probably the greatest center ever (except maybe Wilt). Now, he was a truly well-rounded basketball player.
Once I scored a basket that still makes me laugh.
