Many NBA scouts and executives believe Bismack Biyombo is older than his listed age of 18.

Coaches who have worked with Biyombo earlier in his career while he was still in Congo think he's “no older than 20 at most,” while Biyombo's agent, Igor Crespo, has evidence that proves Biyombo is even younger.

Crespo claims he took Biyombo to a specialist to conduct a bone age study immediately upon his arrival in Spain. The study involves taking x-rays of an adolescent's wrist and hand to see if his growth plates are still open. Because the cartilage in Biyombo's hand hadn't fused at that point, the specialist came to the conclusion that he could be 16 or 17 at most, but not 18, when growth plates are expected to be closed.

This obviously rules out the possibility of Biyombo being five to eight years older than he's listed, as the wild speculation we've seen recently on the Internet indicates. Crespo says he will willingly share these x-rays with any NBA team that requests them.
