Adding up all those contracts

After coming within inches of their fourth Super Bowl victory in franchise history, the Patriots took to the 2012 offseason with re-tooling and re-loading an already talented roster in mind.

Here is a rundown of the Patriots offseason acquisitions, including available contract details. It’s important to remember that many contracts includes incentives that are not necessarily reflected in the numbers below, and that contracts are not fully guaranteed in the NFL. The Patriots will need to trim the roster down to 53 players before the start of the regular season, meaning some of the money invested this offseason will not ever be paid out.

Reserve/Future Contracts

LB/DE Markell Carter: 1-year, $465,000

WR Britt Davis: 1-year, $465,000

OL Matt Kopa: 1-year, $465,000

DE Aaron Lavarias: 1-year, $465,000

LB Mike Rivera: 1-year, $465,000

DB Ross Ventrone: 1-year, $465,000

Total Investment: $2.79M

Quick take: These six players all fall into the developmental category, an area the Patriots have had success during Bill Belichick’s tenure. Ventrone was a human-pinball on the transaction front last season, bouncing between the active roster, practice squad and unemployment.

Re-Signed Veteran Free Agents

WR Deion Branch: 1-year, $1.325M

OL Dan Connolly: 3-years, $9.7M

DT Marcus Harrison: 1-year, $615,000

QB Brian Hoyer: 1-year, $1.92M

C Dan Koppen: 2-years, $3.05M

LB Niko Koutovides: 1-year, $825,000

DT Kyle Love: 1-year, $540,000

WR Matthew Slater: 3-years, $5.4M

DL Gerard Warren: 1-year, $985,000

WR Wes Welker: 1-year, $9.5M

LB Tracy White: 1-year, $890,000

Total Investment: $34.75M

Quick Take: On top of the list of free agents to retain was Wes Welker, and although the negotiations for a long-term deal have been somewhat of a roller-coaster ride, the veteran receiver will be back in New England next season. The Patriots did well to reel in most of their pivotal free agents, although defensive end Mark Anderson bolted for Buffalo, while fellow defensive end Andre Carter remains unsigned.

Unrestricted Free Agent Signings

RB Joseph Addai: 1-year, $1.069M

CB Will Allen: 1-year, $1.025M

LB Bobby Carpenter: 1-year, $775,000

DB Marquice Cole: 1-year, $650,000

DE Jonathan Fanene: 3-years, $12M

TE Daniel Fells: 3-years, $5.25M

FB Tony Fiammetta: 1-year, $700,000

WR Jabar Gaffney: 2-years, $2.3M

OL Robert Gallery: 1-year, $1.8M

WR Anthony Gonzalez: 1-year, $716,000

S Steve Gregory: 3-years, $7.05M

K Chris Koepplin: 1-year, $390,000

FB Spencer Larsen: 2-years, $1.7M

WR Brandon Lloyd: 3-years, $12M

OL Jamey Richard: 1-year, $700,000 (estimated)

DE Trevor Scott: 1-year, $1.15M

WR Donte’ Stallworth: 1-year, $875,000

Total Investment: $50.15 million

Quick Take: The Patriots roster was strong in 2011, and the team held off from spending big during the early part of what was a rapid-firing free agency period. But that doesn’t mean the Patriots didn’t add quality, as several of the above players project to intake important roles for 2012. Notably, Gregory and Lloyd address areas of need from last season.

Draft Choices

DE Chandler Jones: 4-years, $8.17M

LB Dont’a Hightower: Unsigned

DB Tavon Wilson: 4-years, $4.217M

DE Jake Bequette: Unsigned

S Nate Ebner: 4-years, $2.196M

CB Alfonzo Dennard: 4-years, $2.157M

WR Jeremy Ebert: 4-years, $2.148M

Total Investment (so far): $18.898M

Quick Take: It seems only a matter of time before Hightower and Bequette sign their contracts, a process that has been made easier under the new collective bargaining agreement. Contract lengths are fixed (all are four years), and the value is virtually pre-determined by the CBA.

Undrafted Free Agents

RB Brandon Bolden: 3-years, $1.59M (Guaranteed money: $15,000)

DL Marcus Forston: 3-years, $1.54M (Guaranteed money: $10,000)

DL Justin Francis: 3-years, $1.49M (Guaranteed money: $10,000)

TE Brad Herman: 3-years, $1.46M (Guaranteed money: $2,500)

OL Jon Opperud: 3-years, $1.44M (Guaranteed money: N/A)

WR Matt Roark: 3-years, $1.46M (Guaranteed money: $2,500)

OL Jeremiah Warren: 3-years, $1.62M (Guaranteed money: $28,000)

OL Markus Zusevics: 3-years, $1.57M (Guaranteed money: $13,000)

Total Investment: $11.52M

Quick Take: These deals are all spread over three years and are in the same range of total value, so guaranteed money can be used as a metric to measure how the team may value each prospect. OL Jeremiah Warren tops the list with $28,000 in guarantees, which suggests he was a coveted rookie free agent after the draft. The team has had some success with undrafted players before, and may be able to find another hidden gem in this year’s class.
