I'm not sold on the idea that he his gone. I think he wants honest evaluation from the NBA and then make an informed decision instead of one made on assumptions. (As he stated in the article Robowe linked)
Also, why are you putting down playing in Europe. It pays MUCH better and you can still get noticed by the NBA. This information is 6 years old, but still true as far as the discrepancy. "The worst part about basketball players staying in the USA and playing in the D-league is the fact that most D-league salaries range from only $12,000 to $24,000. Average overseas players can get a $65,000 contract with ease. Depending on the league that players get into in Europe, salaries can start as high as $100,000. Not only is there a big discrepancy between the salaries, but the money made in Europe is typically tax free."
