He's quick and skilled enough to play minutes at SF as a 7 foot rookie. You guys should study him more, and think a little bit.
He's more proven than most of the college players in this draft, because he plays in the best league in the world outside of the NBA, as an 18 year old.
He's very tough, he just needs to add more weight.
You don't just dismiss athletic and long and skilled 7 footers because you haven't seen him play college ball 20 times.
