personally i'd deal the draft picks while they are "hot." Whether that is right now or by the deadline. The only thing we all know for certain is they are definitly not hot when the season ends, at least if this last draft was any indication.
It's a gamble regardless, nobody knows for sure what our pick, the Nets, or the Mavs pick will yield, obviously teams will have a better idea by the trade deadline.. but clearly the value could change for the better or worse as to what they are worth right now.
If it was up to me, i'd try to move them before the season begins.
