On the taxes and exchange issues. Obviously with the Dollar declining the worth of the Euro is increasing, making it easier for an owner to pay Lebron $50 million U.S. which is only something along the lines of 32-33 million Euros. So while thats still no chump change, it does make it easier. Also on the tax issue. In the Childress contract for example he is being paid 7 mil a year (I believe). In fact his actual contract is for something like 8.2 mil while the club is just paying the taxes for him. Apparently this is done quite frequently by European clubs in their attempt to acquire top flight talent. So 50 mil for Lebron is really 60 mil, with the club just paying the taxes on excess directly.
I think it would be kind of cool to see Lebron go overseas. It really depends on what his goals are. If its to become the best basketball player, going overseas will tarnish that a bit. (unless of course he wins championships and breaks records in spite of missing prime years while in Europe). However, if his goal is to make money and become a global icon, why not go to Spain, or Greece, or Russia to make that happen.
At the end of the day however I am highly skeptical of LeBron going overseas. While I have no concept of the difference between 750 million, and 1 billion dollars. I believe guys like Lebron, the 1%ers who really are the best in the world only have one stage to prove their dominance on, and that is right here in the good ole NB of A. Winning Euroleague titles, and scoring 90 on some half assed Greek club team wont elevate him to Jordan status. Only rings (about 6) and records will do that.
