I'm going to give up on this thread. To be CLEAR, I don't think its a "two man draft." I do think you have two guys who are going to be sure thing NBA stars. I think you then MAY have other guys who are as good but I think the odds are you have a possible Dr. J and a possible Hakeem and than a drop off to Zach Randolph and then Bobby Dandrige knock offs. The rest of the draft can be good but I think Embiid and Parker are the guys who will have by far, the best NBA careers and I'd be looking to move up to two.
The main point was how do we move up to 2 from say 6 without losing too many assets?
If there is a "Huge" dropoff after #2, you don't. Plain and simple. You can move up, but it will cost you a lot. Probably Rondo and #6, because no team wants to be seen as trading that #2 for a collection of lesser picks or NBA role players in a league where you need multiple stars to win.
My point is that there isn't a huge dropoff (although I highly doubt Embiid goes #2 anyway), and I wouldn't go all out to pay that price. I'd call, and see what it was, but it's going to be too costly to be worth it.
