Re: can Biyombo still grow?
Some doctor apparently did some sorta tests, bone growthplates in his wrist or something, and said the results are consistent with an 18 year old. Of course you gotta figure out who hired the doctor, which I don't know.
I don't know how hold he is, but I do think he's over 18. Not just his frame but his mental makeup. He's apparently extremely acute and mature.
