I don't necessarily disagree with the OP.
Only thing, is Danny, the master fleecer, has the potential to get a return in the next couple of hours that far surpasses what any guy we pick at #3 would do.
I think he's in sort of a Cuban Missile Crisis moment with Dunn at #3. I think he all but has to pick Dunn, unless one of the other top 8 teams makes a solid enough trade back offer.
Dunn, whether he gets traded as we are on the clock, or later tonight, is the third best player right now in the draft, and at the most coveted position, with a weak PG class behind him.
Our contingency plan could be to just keep Dunn, and then flip Smart to another top 8 team for their pick, whether it's Brown/Bender/Murray/Hield.
I wasn't sold on Dunn, but I'm starting to like his more rounded game over Smart. I think Smart is pretty close to his ceiling, and while he may be better than Dunn right now, i'd give it a year or two before Dunn pulls ahead stat-wise.
