It isn't just whether the player is top 15 or whatever, it's how he fits on the team. I'm not sure the player exists that a) is someone whose team wants to move, and b) is someone I'd want for the BKN pick. Next years draft seems like it might be special.
That said, I've noticed during this entire process that, judging by what the media says, there are at least 25 'top five player in the league' guys.
