I wouldn't go that far and blame the kid for the actions of his guardian. IMO he is just a pawn and every time there is a news outside of Thon's court performance, it is related to something Smith has done or said.
Smith appears very arrogant and ignorant of the situation. He acknowledges the fact that BA has no money but will do nothing to change that. BA funding is clearly linked to performance so if potential superstars don't want to commit to the national team due to lack of funds, it says something about them.
Personally I don't think it would put much strain on anyway depleted budget to bring Maker, Simmons and Bolden (at least) back to a camp, fly them to China and join them to the team in June during final preparations for the Worlds. I'd say this would be around $10K-15K considering that they would replace 3 other players, so the difference is actually in the airfares from the States and local flights.
IMO this has nothing to do with funding, this seems more like either requests coming from Smith are unrealistic or Maker (or Smith rather) has no real interest in joining the program. I just think Smith is concerned Thon's stock would go down if he underperformed at the biggest stage. So fair enough, make a decision and stop fueling speculations and blaming the organisation. At least we can then focus on commenting on Thon's on-court performance (more Thon, less Smith) and support those who decide to represent our country.
So to resonate Isaac:
"Why not take the guys who really want to play?"
