We can nitpick about the exact money, but I think we can all agree that falls into the category of "sh!t load" and start from there.
. So we have another 4 months of Free Agency before TC, and just over one month before the draft to get to the 90 man roster, so there will be a LOT of signings left to come.
This period of FA that comes after the signing frenzy of the first week, is usually when BB does his best work. Money should be of no object in any future signing. So there shouldn't be any hurry to get anyone else done unless there is competition for their services
Mangold - Is perhaps the only signing I'd like to see happen at this point. If healthy he WOULD be an upgrade over Andrews. I'm not sure why he wasn't snapped up in that run on offensive linemen early in FA. He was an all pro as recently as 2015. He could be one of those guys who is going to have to wait until after the draft to get a deal.
Revis - I would actually consider bringing him back IF Butler isn't here, and IF we didn't draft a CB who could help right aways, and IF BB is convinced Revis would prepare for this season like his legacy depended on it. IF all those circumstances came together then he'd be a solid Ryan placement on a team without Butler. He would allow the young CB's to continue to develop, add depth, and a wealth of knowledge and experience, He also knows the system and culture.
Of course he'd have to really want to come back and that might not be what he has in mind. He busted his ass in 2014, but clearly he's been in cruise control the last 2 seasons, so another year in the Patriot Way grind, might not be what he wants to put up with. So, even if Butler goes, Revis to the Pats might be a moot point.
Now that Hightower is back, I am happy with our ILB's McClelland is on the cheap for another 2 years (IIRC) and Van Noy for another year. Both have some position flexibility. I would be surprised if we didn't see at least some improvement from both these guys. They aren't guys who get you excited, but were both useful and dependable players. Roberts on the other hand, I really liked. He was very effective against the run already, so I look to see his coverage skills to improve. I think he'll prove to be an effective Hightower back up.
The skill I'd really would like to add to our defense is at the hyprid LB spot. Hassan Riddick might be someone who could fill that in the draft, but I think we'd have to get that #12 pick to get him.
I'm not excited about any of the RB FA's so bringing back LGB is fine with me, and lets see if he beats out the competition again like he did last season.
BTW- I wonder what James White's trade value would be right now. Whatever it is, it is never going to get higher. If we could add a 2nd or 3rd round pick for a superbowl hero it would be a great value. As good a season as he had, I think between Berkhead, Lewis, and Foster, we could cover his production. I really want to see Foster get a real shot in preseason to make the team. Hey, a man has a right to protect his binky.
