The 2019 New England Patriots are a bit different from the team that knocked off the Rams to win Super Bowl LIII. 

Gone (for now?) is Rob Gronkowski. Trey Flowers has also moved on, while Michael Bennett should step in to fill that gap on the Patriots defense. 

Tom Brady also has several new targets at his disposal, from tight ends like Ben Watson and Matt LaCosse to wide receivers like Demaryius Thomas and Maurice Harris.

Who else has come and gone from the Patriots' roster in free agency and the trade market? Keep up to date with all of the moves with this Patriots tracker.

The Patriots acquired Michael Bennett and a 2020 seventh-round draft pick from the Eagles in exchange for a 2020 fifth-round pick. It was a very small price to pay for a talented pass rusher. The 33-year-old defensive end has tallied seven or more sacks in six of the last seven seasons, and he totaled nine sacks and 30 QB hits for the Eagles during the 2018 season. Trey Flowers led the Patriots with 7.5 sacks and 20 QB hits last year. 

Bennett also brings a ton of playoff experience from his time with the Seattle Seahawks and Eagles. He was among Seattle's best players in its Super Bowl XLIX loss to the Patriots.

The Patriots released tight end Dwayne Allen in a move that opened up salary cap space. Allen served primarily as a run-blocking tight end for the Patriots and filled that role nicely. He showed earlier in his career with the Indianapolis Colts that pass-catching is another strength of his game, so his new team should be able to give him a larger role on offense.

Allen spent two seasons with the Patriots.

Trent Brown is off to the Oakland Raiders after agreeing to a four-year, $66 million contract with $36.75 million guaranteed, per ESPN's Adam Schefter. It makes Brown the highest-paid offensive lineman in NFL history. Who will replace Brown at left tackle for the Patriots next season?

The most likely candidate is Isaiah Wynn -- a 2018 first-round draft pick who missed his rookie season with a torn Achilles.

Trey Flowers' loss certainly will be felt by the Patriots after he led the team in sacks (7.5) and QB hits (20) last season. He's one of the best young defensive ends in the league and still has plenty of prime years left. Flowers agreed to a five-year, $90 million contract with the Detroit Lions, where he'll be reunited with former Patriots defensive coordinator Matt Patricia (now the Lions' head coach). 

He'll begin the season on the physically unable to perform list.

Don't be fooled; even though Patterson is listed as a wide receiver above, he was used more as a running threat in the Patriots offense in 2018. Now he's off to the Windy City on a two-year, $10 million contract with the Bears, a deal that reportedly includes $5 million in guaranteed money. 

Patterson had a productive season in Foxboro, with 21 receptions, 42 carries and five total touchdowns, including a 95-yard kickoff return at Chicago, which must have impressed his soon-to-be coach Matt Nagy. And even though Patterson's 28.8 yards per kickoff return average ranked third in the league, he only had 23 kickoff returns all season, less than 1.5 per game. Now the Patriots will need to find another kickoff returner in addition to overhauling the receiver position.

The Patriots didn't let all of their pending free agents get away.

New England re-signed John Simon, a veteran defensive end who played in 11 regular-season games and three postseason games for the Patriots last season. Simon played in just 17.7 percent of the Patriots' defensive snaps but was a solid special teamer and gives them depth at defensive end entering 2019.

The Patriots are bringing back an old friend in Bolden, who spent the 2018 season with the Miami Dolphins after six seasons in New England from 2012 to 2017.

Bolden was a core special teamer during his first tenure with the Patriots and likely will serve in that same role this time around, as the Pats have plenty of running back depth.

Veteran cornerback Jason McCourty is returning to the Patriots on a two-year, $10 million deal, as first reported by NBC Sports Boston's Tom E. Curran.

McCourty was traded to the Patriots before the 2018 season and played well in New England' secondary alongside his twin brother, Devin. Jason ranked as the 17th-best cornerback in the league last season, according to Pro Football Focus' grades, and his exceptional play to prevent a Brandin Cooks touchdown catch in Super Bowl LIII was one of the most important moments in the Patriots' championship campaign.

The Patriots picked up special teams star Matthew Slater's 2019 option. ESPN's Field Yates reported Slater will earn a $400,000 roster bonus as a result. The 33-year-old veteran played very well in the Patriots' Super Bowl LIII victory against the Los Angeles Rams.

The Patriots re-signed wide receiver Phillip Dorsett to a one-year deal. The 26-year-old tallied 32 receptions for 290 yards and three touchdowns last season and looks to take on an expanded role in New England's offense in 2019.

Eric Rowe played in just four games with the Patriots last season due to injury. He signed a one year, $4.5 million contract with the Dolphins, where he'll join former Patriots linebackers coach Brian Flores, who's now the head coach in Miami.

Brown was a four-year starter on the defensive line, but never really lived up to his first-round billing in Foxboro, playing under 44 percent of the defensive snaps last season and totalling a career low in tackles, no sacks and just one quarterback hit. So it's no surprise that New England didn't overbid the Saints, who signed Brown to a three-year deal worth a reported $15 million.

Though Brooks is listed as a safety, he has made his bones as a special teams specialist during his five-year NFL career with the Ravens, Eagles, and Jets. Throughout his career, Brooks has played significantly more snaps as a special teams contributor than as a safety. Now he's headed to the Patriots on a two-year deal.

The Patriots added even more receiver depth by signing Harris, a three-year veteran who had spent his entire career in Washington. Listed at 6-3, 200 pounds, he gives New England some much needed height at the position. 

Harris had 28 catches for 304 yards last season, but really flashed with a 10-catch, 124-yard performance against Atlanta in November. According to Phil Perry, he had just one drop on 29 catchable targets last year, putting him in the top-20 in terms of drop rate among receivers with at least 40 targets.

The Patriots added some much-needed depth at tight end by signing former Denver Broncos tight end Matt LaCosse. 

LaCosse tallied 24 receptions for 250 yards and one touchdown in 15 games for the Broncos during the 2018 season.

The Patriots added former New York Jets defensive lineman Mike Pennel to their roster. Pro Football Focus gave Pennel an impressive 87.1 grade for his performance in 2018.  He did not miss a single game for the Jets over the last two seasons.

Even though Adrian Clayborn wasn't a free agent, the Patriots granted his release anyway. Clayborn later signed with the Atlanta Falcons. 

Clayborn played in 14 of the Patriots' 16 games last season, recording 2.5 sacks while playing in 30 percent of the team's defensive snaps as an edge rusher from the right side.

The Patriots filled Clayborn's void by acquiring defensive end Michael Bennett but still need help up front after letting Trey Flowers walk.

Waddle signed a one-year contract with the Buffalo Bills on March 16 after three-plus seasons in New England.

The 27-year-old was a solid backup tackle last season for the Patriots, who currently have little depth at the position behind Marcus Cannon and Isaiah Wynn and likely will be in the market for a tackle this offseason.

After letting Allen test the free-agent waters, the Patriots are bringing their veteran punter back on a one-year contract.

Allen has been rock-solid over the last few seasons since joining New England in 2013 and gives the club continuity at a position where Bill Belichick covets it.

Jacob Hollister finished his career in New England on the injured reserve list. The Patriots placed him on IR before the postseason started, and the backup tight end won't be wearing the red-white-and blue next year. 

In exchange for Hollister, the Seattle Seahawks sent a seventh round pick to the Patriots. The Pats signed Hollister, who went undrafted out of Wyoming, in 2017. He recorded eight catches for 94 yards in 23 games played.

The Patriots secondary was one of many strengths last year, and they should have another strong, deep group in 2019. 

New England re-signed cornerback Jonathan Jones, who played in all 16 regular season games in a career-year. Jones was also huge in the playoffs, starting two of three games including the Super Bowl. Against the Rams, Jones recorded eight tackles and a sack. 

Jones, 25, also contributes on special teams.

Demaryius Thomas, who played his prime years in Denver, is joining a long list of veteran wide receivers who the Patriots took a flyer on. Some — Randy Moss, Josh Gordon, Brandon LaFell — have worked out. Some others — Chad Ochocinco, Reggie Wayne, Eric Decker, Torry Holt — haven't. 

So far, Thomas is trending in the wrong direction. The 31-year-old will begin training camp on the physically unable to perform list, which is typically valuable for receivers to learn New England's complicated playbook and for developing chemistry with Tom Brady. Historically, Thomas has been Mr. Dependable, as he's played in 16 games six of his last seven seasons (he played 15 last year). 

Last year with the Broncos and then with the Texans, Thomas he recorded 59 catches for 677 yards and five touchdowns.

Ben Watson, who began his 14-year NFL career in New England, will be reunited with Tom Brady in 2019, though he will miss the first four games of the season due to suspension.

Old Reliable is still dependable, as he's played all 16 regular season games in each year since 2014. Last season with the New Orleans Saints, Watson grabbed 35 catches for 400 yards and two scores.

Without Rob Gronkowski, New England is praying Watson still has some juice left in the tank, and that he can re-ignite the chemistry he developed with Brady in the early 2000's.

It was always Stephen Gostkowski's "first choice" to return to the team that he's won three Super Bowls with, according to NFL Network's Mike Giardi. 

Still, the 35-year-old kicker hit the open market this summer before agreeing to a two-year, $8.5 million deal with $5.5 million guaranteed.

The biggest departure for the Patriots this offseason was its biggest personality. 

Even though the will-he-or-won't-he unretire buzz continues through the summer, the Patriots will be without their superstar tight end for at the very least the start of the 2019 season. 

And in typical Gronk fashion, he went out with a bang, as arguably his greatest catch came in the last game he played — in the Super Bowl win over the L.A. Rams. 

If this is really it for Gronkowski, the surefire Hall of Famer finished in the top-five among tight ends in both touchdowns (79) and yards per game (68.4). Gronk played nine seasons, all with New England.

The Patriots signed Dontrelle Inman in an apparent attempt to add receiver depth on the outside.

The 6'3 wideout recorded 28 catches for 304 yards and three touchdowns in nine games (four starts) last year in Indianapolis. Since entering the league in 2014, Inman has made stops in Indianapolis, Chicago, San Diego and Los Angeles (LAC).

It seems clear that there are no hard feelings between the Patriots and linebacker Jamie Collins even though New England shipped him off to Cleveland in 2016. 

The linebacker began his career in New England and is now back with the team after two-plus productive seasons with the Browns. Now, Collins has the Pats' coaching staff "fired up" with his impressive training camp showing. 

Collins, 30, had 104 tackles and four sacks last year. His versatility will likely aid a defensive front dealing with departures to defensive end Trey Flowers and defensive tackle Malcolm Brown.
