I would gladly trade both picks for either Sullinger or Jones (Perry). The other guys on the list, not so much. They both have their risks, but top-5 talent. At this point I think Sullinger is becoming underrated. He can score AND rebound. Not every big man has to be Blake Griffin and this whole "can't score over length" thing is out of control. I don't think it's clear that Barnes, Beal, Robinson, Drummond or even Gilchrist will be better. Those guys all have flaws as well - Barnes has yet to live up to his billing, Beal is a shooter who didn't shoot at times, Drummond is ALL upside, Gilchrist has a little Battier in him (i.e. motor is #1 skill), Robinson struggled at times in the tournament but nobody said a peep about it. I'd be psyched to draft any of them, but point being if Sullinger drops out of that group I'd want to swoop in.
Perry Jones would worry me, but again I think you're talking about a guy who could fall short of his potential and STILL be much better than anyone picked after 20. What I do like about him... he would look fantastic running the break with Rondo and Bradley. Those 3 would be unstoppable in the open court. Someone's going to roll the dice on him though, I bet inside of the top 10.
There are hardly any guarantees in the draft, and certainly none past top-10, so if we could get either of those guys, we should roll the dice. Talent trumps in the NBA.
