First and formost is resigning Vince Wilfork. Remember yesterday's game had an unhealthy Brady, Wilfork and Warren. Thomas has played his way out of Belichek's scheme of things and will be released, further freeing up money.
The offense with Brady having more confidence in his knee and Welker coming back mid year will be good next year if they can establish a solid running game. Edleman seems like he can be Welker Jr., but needs more maturation as a WR. Free agent running backs include Pierre Thomas, Ronnie Brown, Cadalliac Williams, Leon Washington, Chester Taylor.
As per defense...let's start with the line as Julius Peppers could be a free agent. Elvis Dumervil is also available, as is Marcus Spears, Adewale Ogunleye, Vince Wilfork, Richard Seymour and Barry Cofield.
Line backers include: Shawn Merriman, DeMeco Ryans, D’Qwell Jackson, Bertrand Berry, and Derrick Johnson.
What does worry me is Mankins on the FA list as a prime of career OL, would be nice to keep.
But building up the defense is key to this.
