I was actually thumbing through this article today.
As far as Korver being the representative I don't think it means anything. I think the magazine was literally getting in contact with whatever players they could get to agree to appear. I mean, DaJuan Summers is representing the Pistons. I feel like I pay a lot of attention to the league and I don't know who that is.
The other interesting thing about the players mock draft was that, to a man, every player picked guys who they wouldn't have to beat out in the event they were drafted. This makes a certain amount of sense. Korver's job with the Jazz looks a lot more secure if the Jazz take Udoh than if they were to take Luke Babbitt for instance.
Other instances, where this came up: Thaddeus Young lobbying for Derrick Favors over Evan Turner (drafting Turner probably sends Young to the Bench unless Iggy is traded). Dejuan Summers lobbying for Cole Aldrich at #7 (Summers is probably barely holding onto an NBA job as it is, drafting a player at his position would probably get him released). Kevin Love, learning from GM David Kahn, picked three wing players.
Biggest WTF: Brandon Jennings selected "Tiny Gallon" with the #15 pick. Gallon isn't even a lock to get drafted as of this writing.
