I think he will balk at the cost of moving up in this draft. Last year it was a little different there was no one at 21 worth taking and we desperately needed a PG. This year we don't desperately need any starting positions and there is much more talent around 21 where the GS pick figures to be.
Uhh, if we have something like the 8th and 14th pick, and we want the 6th pick (we are worried that 7th pick wants our guy), the person at 6 knows there guy will be there at 8, they would trade the pick. Those scenarios aren't that unlikely.
