UFAs that I like, trying to channel BB (likely unsuccessfully):
RB: J. Rogers, B. Cunningham (Pats like him, had him in for visit last yr). Draft RB rounds 2, 3 or 5.
WR: K. Wright, P. Garçon, B. Quick, resign Floyd
TE: R. Griffin, J. Doyle, L. Willson. Williams will be back as blocking specialist.
OL: J. Hawley (Center, TB....tough SOB, more physical than Andrews). OG and OT depth in draft. Guard and Tackle depth in draft.
DE: C. Campbell (likely too pricey, W. Gholston (young, ascending, perfect size for Pats DE at 6"6', 180....really want him opposite Flowers)
DT: J. Hankins, re-sign Branch
OLB: Meh. Draft and/or post-June 1 cuts.
ILB: resign/tag Hightower, Z. Brown (undersized for Pats LB but I'm sure that BB took note of 28 tackles total in the two Pats games this year).
S: Resign Harmon
CB: Prefer to resign Ryan but he may be too pricey. High tender or extend M. Butler.
D. Butler (second go-round, this time as versatile slot CB with Rowe as CB2 on outside if Ryan leaves, price will likely be reasonable). D. Shead (will start year on PUP with ACL but value signing for second half of season because of injury). Cyrus Jones' development into top 4 CB will be key.
Some Comments on your thoughts
RB's - Keep what you have. LGB you can keep for under 2MM on a one year deal, or what amounts to a one year deal. Otherwise see what you can find at the end of the draft. I don't see a FA RB here unless LGB leaves
WR's Keep it simple - Resign Floyd. He has skills and size your other WR's don't. If you do we will be OK at WR - No FA's. then draft the best WR who needs a red shirt year on the 3rd day. (an injury dropper) There is no reason for new WR's on this team beyond development for the future. Edelman, DA, Hogan, Mitchell, Floyd is as good as we could hope for as far as diverse skills and depth. The only concern there is beyond 2018
OL - It is 2 to 3 years too early to think about using a high pick on a OLman. Solder had a bad GAME, not a bad year, quite the opposite. Mason was solid all year, but if we need a more physical OG, then don't forget about Tre Jackson. I think that will be an interesting competition if he can come back healthy.
Getting more physical at C would be my major hope for the OL. Your FA idea could be good. I don't know the player you suggested, but I'd be open to it, if he's better. Otherwise a 4th or lower draft pick would be OK if that person exists. If not then Andrews has proven he doesn't suck.
TE- Even if Bennet is gone, we need to see what the TE's we already have on the roster can do. Lengel, Scruggs, Williams will all be at TC next season and all offer some degree of different skills. I'm not one looking to draft a TE high or assume Gronk won't last the season. IF Bennett isn't signed (BTW $5-7 MM is likely the Pats valuation of him on a 2-3 year deal), then a guy like Floyd would be perfect to replace Gronk to run his off the line routes.
DL - I like the Gholston idea, but a lot depends on how they feel about Grissom's development, since he is a longer version of Flowers, who hasn't developed as fast, but has similar raw athletic talent, just not as good a "football player". I think Sheard has played himself back into the middle of FA pass rushers, and could be signed for less than people expected before the year started. Ninko is old, declining but still a valuable situational piece, but next year should be his last. I expect Long to retire.
This draft is deep in outside pass rushers. I expect our first pick in this draft to be a DE or LB.
DB's If it's not a DE, or LB, it could be a CB simply because there are so many of them. I expect Butler back under one of several conditions. I expect Jones to rebound next season into a top 3 CB. I expect Ryan to either be back or replaced by a combination of a first or second round Draft pick and Rowe.
I think Harmon is eminately replaceable. It could be as easy as Richardson, or Ebner, or someone in FA or the draft. Either way Chung and Dev will be the starters.
LB- I think Van Noy is a great athlete, but without any real football instincts. He's a tease, who makes some good plays but isn't consistent enough. We need an upgrade at the position, unless BB feels he can improve with a full season in the program. Brown obviously has great instincts but not the size. I think we have that skill set on the roster in Roberts. It just needs to get more experience. Besides, I'd like to think Mingo can be developed into something more than ST's player.
