Rams: The Rams need to do one thing. Keep keep keep. You cannot let any of your team go. Robert Woods needs to be re-signed. Add some depth and go do your thing next year.
Seahawks: The Seahawks story will always be the same. They need O line talent, however they always heavily invest in the line but at this point you have to keep taking shots and hope new coaching improves your trench. The Legion of Boom is over, you need to find a new piece on defense. Perhaps make a trade? It is said Marcus Peters is on the block in KC, Richard Sherman for Marcus Peters straight up, sounds intriguing to me.
Forty Niners: The Niners have the piece to start building towards a Lombardi in Jimmy G. They now need to focus on everything else, the defensive side of the ball has been built through the draft and is less of a focus than the O line and tight end positions should be. The Niners could also use some veterans on the team to help the young guns in the bay develop.
Cardinals: The Cardinals need to get a QB. Case Keenum would be a good answer for the Cards. However the Cardinals need an offensive line. Adding a quality backup behind injury prone David Johnson and cutting ties with Adrian Peterson should also be priorities for the Cardinals.
