FOXBOROUGH, Mass. -- Since he was hired by the New England Patriots in 2000, Bill Belichick has made 121 trades. His wheeling and dealing has intensified since September 2014, as he has made an NFL-high 21 trades that have involved a player leaving or coming to New England, according to ESPN Stats & Information research.

Here are some of his most notable deals over the past decade, and how they worked out for the team.

Date: Sept. 11, 2006

Trade: WR Deion Branch shipped to the Seattle Seahawks for a first-round pick.

Result: The Patriots finished 12-4 and advanced to the AFC Championship Game, losing to the Colts 38-34. Reche Caldwell led the Patriots with 61 receptions, but it was a year in which the Patriots pieced together their receiving corps, which ultimately led to a splurge the next year with the acquisitions of Randy Moss, Wes Welker and Donte Stallworth. The Patriots used the first-round pick on safety Brandon Meriweather, who didn't meet first-round expectations.

Date: March 5, 2007

Trade: Acquired WR Wes Welker from the Miami Dolphins for second- and seventh-round picks.

Result: While some analysts initially believed the Patriots overpaid for a slot receiver, Welker went on to set a franchise record for receptions (672) from 2007-2012. The team played in two Super Bowls in Welker's tenure.

Date: April 29, 2007

Trade: Landed WR Randy Moss from the Oakland Raiders for a fourth-round pick.

Result: Moss set the single-season NFL record with 23 touchdowns that season, as media-driven questions about how he would fit into the team’s hard-driving culture were quickly answered with the team advancing to Super Bowl XLII and losing 17-14 to the New York Giants. Moss re-signed the following offseason before he was traded to the Minnesota Vikings in 2010.

Date: Feb. 28, 2009

Trade: Shipped QB Matt Cassel and LB Mike Vrabel to the Kansas City Chiefs for a second-round pick (safety Patrick Chung).

Result: Cassel wasn’t going to be part of the team’s plans, but the inclusion of Vrabel in the deal was a shock based on his significant contributions to the team (2001-2008) that included three Super Bowl championships. The team badly missed his leadership in a 2009 regular season that ended with a 10-6 record and wild-card-round playoff loss to the Baltimore Ravens. In the big picture, Chung has become a key cog for the team in his second stint (2014-present).

Date: Sept. 6, 2009

Trade: Sent DL Richard Seymour to the Oakland Raiders for a 2011 first-round pick (LT Nate Solder).

Result: The Patriots missed Seymour in the short term as the 2009 season fell short of expectations (see above), but made the move because they felt they wouldn’t be able to reach a contract agreement with him. The team hasn’t had a season worse than 12-4 since as Solder became their starter in 2012, winning one Super Bowl (in the 2014 season).

Date: Aug. 26, 2014

Trade: Shipped G Logan Mankins to the Tampa Bay Buccaneers for a fourth-round pick and TE Tim Wright.

Result: Mankins was a locker room pillar as the deal came near the end of preseason and rocked the players in its suddenness. Similar to the Seymour deal, finances drove the team’s decision. As it turned out, the Patriots went on to have one of their most memorable seasons in Belichick’s tenure, beating the Seattle Seahawks 28-24 in Super Bowl XLIX. Wright wasn’t a huge factor, while the fourth-round pick turned out to be DE Trey Flowers, who is currently on the roster and being utilized as a sub rusher.

Date: March 13, 2016

Trade: Shipped DE Chandler Jones to the Arizona Cardinals for a second-round draft choice and G Jonathan Cooper.

Result: This falls into the “incomplete” category, but the early returns are positive for New England: a 7-1 record and the draft pick traded and turned into starting guard Joe Thuney and promising receiver Malcolm Mitchell. Meanwhile, Cooper is no longer with the team. Like many of the other deals, finances were a big part of the consideration as Jones is scheduled for unrestricted free agency after the season, and the Patriots used some of the salary-cap space to sign others (e.g., DE Chris Long).

Date: Oct. 31, 2016

Trade: Swapped LB Jamie Collins to the Cleveland Browns in exchange for a compensatory third-round pick.

Result: To be determined.
