While I agree with much of that, the pick versus the already drafted prospects part, I think much of that depends on how they perceive this next draft, and how they perceive whoever maybe available from those 14-16 drafts and who may be avaible as the add on instead of say a 2nd rounder.
For example say they do take back a 2nd, likely a late one instead of say Bennett, can they somehow find another Fox type using that late 2nd if they also combine it with their own 2nd?
For sure if there is another Fox like player (say a forward instead) who may become available, I'd want the picks to make that sort of deal should it come about as those two 2nds, or one 2nd and Bennett is not worth as much as a Fox like player.
I guess I think at the deadline the already drafted players being made available from those who are renting are almost always going to be like secondary or B level types, where as during the summer leading up to the draft teams start to think about, well things like do I have to trade a Fox? Something they were not going to trade at a deadline because they still had time to try to sign him, and were more focused on the playoffs at hand.
Seems like GMs wait until they are absolutely desperate to trade anything of real value, and I'm not sure those teams feel the desperation to do so at the trade deadlines where as during the summer that desperation starts to manifest itself.
