Out of everyone on that list, as soon as FA starts, the only guy I'm interested in is really Nick Mangold. If I'm making an improvement at CB/OLB, then I want to go big or go home at each of the respective positions. I'm looking at the market for the top FA OLBs/CBs and if the price is right then I'm certainly for bringing them in, if not then I'm okay with looking towards those other guys, but Mangold would be a solid signing, he may have declined but we need as much maulers as we can get here. I haven't kept up with him honestly but I know what he was at his best, even if he's declined a bit, I just want a Center who can push the pocket and help big on inside runs.
I just don't know about Ngata, I don't know how much he has left and I think he can delay bringing a guy like Michael Pierce who has big potential into the mix. I just don't think Ngata is a need if we bring back Brandon Williams as heartbreaking as that sounds.
Back to Mangold, a lot of his struggles were attributed to his injuries, and it's not like the Jets are desperate to let him go, they have weighed in keeping him at a restructure but the cap savings is too much to do so. Personally I would say bring him in for a visit and don't let him leave till he signs.
