From experience, people get pretty bored with this draft after its concluded. Last year we did little write ups for each team, one per day. We made it about 8 or 9 days before people lost interest and gave up entirely.
My point, I guess, is that if people want to crown a "winner" or multiple "winners" in various categories, it should be able to be wrapped up quickly upon conclusion of the draft. Anything that requires the participation of all 30 GMs, and multiple rounds of voting, likely isn't going to work as well as it looks on paper.
Still, if people want to attempt to prove that last year was an aberation, and want to give the above suggestion a try, I'm on board.
