Red mentioned it in the day 2 draft thread - with the way the NFL is handling the picks, delaying their announcement until they've got all the videos and commercials out of the way, is it chancier for teams to trade up?

Are teams told who the picks that haven't been announced are? With 2 or 3 picks in limbo during those waits, it seems like they wouldn't know who is left on the board - a team could conceivably trade up to get a player who's already gone, that would make them pretty wary.
