Agree with BWC's take on ANA moving up. There only incentive to move up would be if they a really strong thought on ED vs AL. Add in that the way a deal gets done is if the Hawks evaluate the players differently, and it's possible that someone else wants to pay to move up to #2.
Purely theoretical example: Hawks love ED, and ANA loves AL (obviously - they don't tell each other their thoughts initially). Verbeek approaches KD about the possibility of moving up. KD would require PV to tell him who they're interested in. If Verbeek says ED, KD would say "sorry, no deal available" or words to that affect. If Verbeek says AL, they might work something out, but PV isn't going to pay a huge premium, (like EDM #1 DP), because he knows that if he said the player the Hawks were interested in he would get shot down. If he doesn't get shot down, he knows the real risk would be a team like Columbus or MON might try to move up into the Hawks spot, so he'd be moving up strictly for insurance to make sure that didn't happen. At least, that's the way I see it.
My assumption is that KD would only make a move if Verbeek would tell him who they're going to take. And my understanding of the GM "fraternity" is that GM's trust each other in this type of situation. If that's not true - there's no deal to be made.
