4. Keyonte George
The Jazz clearly believe George is the real deal. At least, for now they do, and he has shown promise as a combo guard scorer. If George rewards their faith in him, that might just be enough for Team USA
For the time being, there's no telling what George's ceiling is after only one NBA season. The results are exciting and encouraging, but much like with any young NBA player, there are some warts. If he can iron those out, there's no telling how good he is going to be.
If George has a high enough ceiling as a scorer, that just might be enough for them to convince Team USA that he's worth checking out.
