May or may not be the right thread for such a question, but, regarding on the clock trades, particularly one where a person is trading up one spot when there is one particular player they want, and they don't want him to get nabbed before their turn. Why not just let the guy make his pick: then, if he doesn't pick the player you wanted, then great, you gave up nothing. And if he does take the guy you wanted, can you not still offer him your pick that is now on the clock, plus whatever extra, in exchange for that same player that he now owns?
I guess the difference is, if you make him the offer for his pick before he has named his player, he may be more inclined to do it, because he knows there is some chance that you may want someone different, and he'll still get his guy, plus whatever bonus you're throwing in.
Or, is there even some rule (written or unwritten) that drafted rookies shouldn't be traded during the draft? Don't see why that would be the case, but maybe.
