I'm not an expert by any stretch of the imagination, but here is my two cents:
Brandon "Bam" Childress, WR - Re-signed to practice squad
re-signed, P-squad eligible, but competitive in TC with a full off-season work-up.
Randall Gay, CB - Re-signed
Gene Mruczkowski, C - Gone
re-signed for TC competition and to keep him under development for the shadow roster.
Guss Scott, S - Probably gone ala Hakim Akbar
re-signed, did well in limited play, cheap.
Santonio Thomas, DT - Gone
re-signed, cheap, did well in TC before injury, creates good competition after a full off-season program.
Billy Yates, G - Re-signed to practice squad
P-squad ineligible, re-signed for TC competition and shadow roster development.
Tom Ashworth, OT - Re-signed
Matt Chatham, LB - Re-signed
Troy Brown, WR - Re-signed (probably would've retired with a SB victory, not going out with the fumble, no way)
Andre Davis, WR - Re-signed
competing for no. 3 WR, showed good STs, KR, role play skills, needs more pitch and catch with Tommy.
Don Davis, LB - Gone
re-signed for TC competition, offered a asst. trainer slot if he doesn't make the roster.
Tim Dwight, WR - Gone (didn't he say he would retire after this season?)
retire? not that I heard, good role player, good downfield blocker, taught Branch something about running a CB off on running plays - re-sign.
Heath Evans, FB - Gone
re-sign, good project, needs blitz pick-up work, good power runner with speed, needs blocking work, good receiver.
Christian Fauria, TE - Probably gone, wouldn't mind seeing him come back though
re-sign for TC competition, great depth at 3rd string this year, good role player too. Has been a great help in developing the younger TEs per BB.
Doug Flutie, QB - Retiring, though I hope he reconsiders, gotta get that ring, Doug!
David Givens, WR - Gone, will probably be offered more than the Pats are willing to give up, hope I'm wrong
Make him a decent offer and hope like heck, he and Deion and Tommy get inside each others heads well.
Artrell Hawkins, CB - Re-signed
Stephen Neal, G - Re-signed
Hank Poteat, CB - Gone
TC competition, shadow roster development.
Chad Scott, CB - Gone
played well in limited time, experienced in secondary where we need it, tall CB who can play - re-sign.
Michael Stone, S - Gone
On track to become new STs Captain, great on coverage, good run support at SS, needs tackling drills in open field, work at coverage, work in BB's system.
Ross Tucker, OL - Gone
TC competition, shadow roster development.
Adam Vinateri, PK - Re-signed
who's he?
Monty Beisel has also almost certainly played his last game in a Patriots uniform. Same with Tyrone Poole, who may as well just retire so he can stop whining about being homesick. I don't think Bethel Johnson will make the cut next season either. Good riddance to those three.
Beisel, improved greatly over course of year, needs full off-season for strength/weight improvement, already signed. Poole, if he wants to come back let him compete at Vet minimum, played well against Oakland, the venom directed at him is a puzzlement. Bethel is signed and cheap, had a poor health year, needs route work and better discpline, played well on STs.
