Lets not forget who Collins is now:
A 7'0 rim protector who has the lateral quickness to guard PFs, can shoot 3s and probably has some untapped passing ability.  And he proved this against the best teams in the country during the tournament.  In Summer League, he didn't have much space to work with because the guards were trash, and he didn't produce on the block because he that isn't who he is, and it's not who we need him to be.  Sadly, a couple Summer League games, coupled with the fact that he's white, has caused some "fans" to be down on him.
This is a dude I could see playing 30min in a couple years while scoring 15pts on 50 FG% and 37 3pt% with top notch rim protection.  He has that ability.
