More and more, I'm really thinking that we should look to trade back in the 1st round.
Feel free to play around with the numbers, but the bottom line is, at #15, the value for that pick would be trading it for #25 and #57 (no we won't be getting those particular picks, Houston has them, but you get the idea, play around with the numbers) which I would do in a heartbeat. There's going to be plenty of value in the 1st/2nd round it appears, so getting more picks is the way to go, particularly when you consider the complete talent depletion that we have, we seem very primed to do so.
This is of course all contingent on how the board plays out. If Reuben Foster drops unexpectedly, then by all means, stay put.
