the kid looks skinny as a rail. most centers and pf in the nba would be able to push him out of the paint. how he could hope to consistently rebound in the nba is beyond me. nor do i see him be able to box out opposing players.
plus, he doesnt seem to move well to play defense.
based only on the video he parks under the basket (hello 3 second rule) and waits for someone to lay the ball up. then he can block it. one trick dog. a dramatic trick, but not enough to be on an nba roster.
in 10 minutes of play he might block 2-3 shots. but how many rebounds would he give up? how many defensive switches would he miss?
no rebounds, no offense. no strength.
i dont see that he would be better than erden or parakhouski. they are strong enough to at least make other centers work to move them out of the paint. plus, i would be very surprised if they do not out rebound hamady.
sorry, but not convinced without seeing more on hamady.
