He is still young, his NBA dream is not over yet.
As long as he continues to play, he will continue to learn and eventually improve, and maybe a few years from now we will see him as the first pure-blooded Filipino in the NBA. He got the height, he can shoot outside, what's lacking in him is his maturity and which can be earned through experience, also, he needs to grow his body.
It may not be over but he's running out of time. He should be tougher than he was as his stance so that scouters will get him.
He is unlucky and undrafted but not every good player gone through in draft phase.
He needs to become thick so that he is ideal to any team that will want to get him.
