Also it's brought up every time someone mentions biyombo, but his lack of height is negated by insane length. 7'7 wingspan. 9'3 standing reach.
Then why has he not dominated? Thus far total success has been elusive for him though he shows talent in some areas.
Throughout history just how many big men, from ages 19-22, have "dominated" the league? Like you also said, "he shows talent in some areas", so it's all about forward thinking and trying to forecast his development during the life of the contract.
few outside of the big name centers that came out in the 80's and 90's - who were closer to 22 than 19.
having said that, there's a number of guys who've come into the league and looked much better than Biyombo when they were 19-22.
still don't see the fascination for this kid. blocks shots. swell. doesn't rebound particularly well. offense is non-existent.
while the contract proposed isn't a backbreaker by any means and wouldn't cause me to swear at it being a horrid deal, I'd still have to question why we'd sign someone like him for that much. for my money, I think Zeller's the better backup center.
