I'd extend DJ Reed and Michael Carter before I overpaid for most of this FA class
I wasn't enamored with the T options in this FA class but I would have been much happier with the guards we couldn't afford (especially Onwenu, Hunt, or Runyan) over whatever deal we gave the Ravens' cast-off penalty machine, or having the financial option to be competitive for another WR which we really freaking need.
Reed might be a good option for that but that's assuming he wants to do the team a favor with a friendlier contract. He's only 27 and he can easily get another big deal after this season. Just because it would be great for the team doesn't mean it would be good for him, especially with him heading into free agency when the Jets are possibly resetting with a whole new front office and coaching staff. Does he really want to be locked into that?
Carter is in the last year of his rookie deal, I'm not sure how likely he would be to agree to a deal actually lowers his cap number this year when he's on the cusp of his first free agency after playing for a team that has been a excrement show.
Mosely is really the only one on the roster who was poised to do the team any favors. He's likely in the last year of his prime, there's actually incentive there for him to extend for more guaranteed money from us vs. any of the other names mentioned here.
