I agree with all of the above. In addition to what you are saying however, I would hope that if we get a vet OLB, we use the 1st round pick on something else unless a guy that CSP absolutely loves slides down to us. There is a chance the top 4 OLB prospects will be gone by 15 and unless Lane Johnson is there I would be in favor of gathering more picks
I don't see us trading back. Payton is an aggressive guy and it shows through in the draft. We often trade up as well as swapping our higher pick next year for someone's lower round pick this year.
I think someone pointed out only one instance of us trading back and it wasn't in a high round.
I see it as much more likely we trade up to get a guy we really like(like the Ellis deal, but hopefully with much better results).
Assuming we are targeting OLB heavily in the first, if one of them is there at 9 you could see a move.
