Can we, therefore, agree that the issue really isn't "Levi for a pick", but instead, "Levi for the elevation of an existing pick?"
Then the issue becomes: "Which is better: (a) getting an extra draft pick? or (b) elevating a pick one pick (or possibly two picks) higher?"
That's a legitimate question, but the inference "that we got nothing for Levi" isn't quite accurate.
A is better imo. Most people have felt we'd of gotten an extra 5th or extra 6th. Thus the details of the trade are about either gaining that 5th or 6th, or gaining that 5th or 6th by giving up our own.
If that moves down to a swap, then we go from having either two 5th's or two 6th's to having one 5th or one 6th, but it being a few picks higher. This is less likely to impact your draft then gaining an additional pick(and I'm going to go on a limb and have it be where we have the right to swap if it would be higher or keep our own). [Which also might mean that if you can't swap because their pick is lower...then you do indeed receive nothing...so it is possibility]
But getting an additional pick means you get an additional player and at roughly equivalent draft position that we expect our swap to get us. Especially since the lines start to blur on players that far down in the draft.
I don't agree that it was for nothing (though it is possible), just less then we first suspected because I consider B less then A. Especially when you can get two A's that are drafted in a similar spot to one B.
Also all this comes down to is appearance. In reality the only thing that matters is if any of these picks can actually turn into productive players.
So it looks worse when you consider that when it comes down to brass tacks in evaluation, two picks is more likely to make an impact then one.
There's also other scenarios which could increase the value of a swap. Perhaps it's a swap of a 3rd or 4th round pick. That would mean more then a swap of 5th or 6th.
That would be an interesting question. Would you rather have an option to swap up 1-31 places in the 3rd or 4th round, or get an additional pick in say the 6th round?
That's the thing in the draft, on paper, trading down means you get the worse player...in reality there is the possibility that you trade down and still get the better player. So no matter what it all comes down to how you draft. Given slight differences I prefer more picks and given what stage we are in the new regime I would think more picks would be better. But it all boils down to, when you pick, are there NFL players sitting there capable of being picked, and are those the guys you pick?
