IMO, you should be able to do better than Lynch for either QB. I think you can get more towards a Blount/Reggie Bush/Tim Hightower tier of RB.
Maybe I'm just not a Lynch fan but I do not know what to make of the Seahawks offense right now. Perhaps wait after Week 1 games are done then do a trade offer.
