FOXBOROUGH — In just two months of offseason workouts and 1½ weeks of training camp, the Patriots have already seen everything there is about the Martellus Bennett Experience.

And the Patriots’ new tight end is nothing if not an experience.

They’ve seen the tantalizing size and athleticism he can bring to an offense. Bennett and Rob Gronkowski give the Patriots two 6-foot-6-inch tight ends with a Pro Bowl on their résumé, a combination that could be impossible for opposing defenses to stop. That potential was on full display during Friday’s intrasquad scrimmage, when Gronkowski caught the first pass of the day for 25 yards up the seams, and Bennett took a simple square-in about 40 yards on a catch-and-run.

The Patriots have also seen Bennett’s thoughtful side. He recently self-published a children’s book, and in June penned an article for The Players’ Tribune titled “Dear Black Boy,’’ intended to serve as support of the Black Lives Matter movement and words of inspiration for young black males in the wake of the Louisiana and Minnesota police shootings.

And, last week, they saw Bennett’s self-destructive side, the side that has divided locker rooms, turned his coaches against him, and sent him packing from Dallas and Chicago.

It came in the form of an ESPN The Magazine article about Bennett and his brother, Seahawks pass rusher Michael Bennett. Dining together with a reporter at swanky Los Angeles restaurants, the Bennett brothers removed their filters and took cheap shots at other players around the league.

Michael Bennett called Jay Cutler, Martellus’s quarterback the last three years, the “worst quarterback in the NFL.’’

“I’d be open and he’d throw into double coverage,’’ Martellus chimed in.

They took shots at Rams coach Jeff Fisher.

“If a QB went 7-9, he’d never be able to find a job,’’ Martellus said.

They took shots at Eagles quarterback Sam Bradford, who staged a brief holdout this spring after the Eagles drafted Carson Wentz.

“Vicious. Competitive,’’ Martellus said, tongue firmly in cheek.

They took shots at J.J. Watt.

“Corny,’’ Martellus called him. “Half of the NFL is corny, though.’’

And Martellus got in one last shot on Jason Witten, whom he publicly clashed with during their four years as teammates in Dallas.

“I hated Jason Witten. I appreciated his game, but I always hated him,’’ Martellus said.

The article was supposed to be a day-in-the-life look at two of the NFL’s most fascinating personalities, but instead portrayed the brothers as unprofessional and a bit narcissistic.

“I feel like I’m the Kanye of the NFL,’’ the article quotes Martellus.

It’s an odd tactic for two players who are looking for new contracts — Martellus is in the final year of his deal, and Michael is angling for a pay raise from the Seahawks.

Naturally, the reviews of the Bennetts were not positive, particularly from ex-players and coaches.

“They’re two really smart guys, they’ll be very successful when their careers end,’’ former coach and current ESPN analyst Herm Edwards said. “I’m just a big believer that words are very powerful, you have to watch your words. If you have nothing good to say about somebody, just don’t say anything. It speaks on its own.’’

Cutler, to his credit, took the high road when asked about the comments.

“Most receivers and tight ends [think they] are always open. Hopefully Tom [Brady] can do a better job of finding him than I did,’’ Cutler said.

On Wednesday, Martellus Bennett expounded on why he and his brother always have something to say. On Thursday, Martellus declined to respond to any criticism, replying succinctly, “I’m not tripping.’’

“The way me and my brother have always been is, speak our minds and stand for what we believe in and stand for something,’’ he said. “I learn from guys like Muhammad Ali, Shaq, and those guys growing up. All those guys were able to make a difference in the world, and whether it was penning a letter called, “Dear Black Boy,’’ that I put in the Player’s Tribune, or my brother talking, wherever he may be, we believe in these things and we believe that we can make a difference.’’

OK, but there’s a big difference in speaking out for truth and justice, and cheap-shotting your former teammates and other players around the league. The latter is a terrible way to build camaraderie and trust in an NFL locker room.

Whether he meant to or not, Bennett has now sent the message to every player in the Patriots’ locker room — you, too, might one day be the recipient of a verbal sucker punch.

The Patriots knew what they were getting when they traded for Bennett in March. He has 19 touchdown catches over the last four seasons, has the potential to put up huge numbers in the Patriots’ offense, and serves as insurance in case Gronkowski suffers an injury.

They got him for just about nothing, receiving Bennett and a sixth-round pick in exchange for a fourth-rounder. And Bennett has been a pleasure so far, bonding quickly with Gronkowski and fiercely studying his film and playbook.

“I study the game. Every single day,’’ Bennett said. “We’re walking down the hallway and I have my iPad open, I’m studying plays. I’ve seen every catch that Aaron Hernandez made in this offense. I’m still a student of the game, just like I’m a student of life.’’

But the more Bennett opens his mouth, the more he’s looking like a one-year rental than a Patriot For Life. He wants a big payday that the Patriots don’t usually provide, and has a history of causing trouble with his words.

In January 2009, the Cowboys fined Bennett $22,000 for an explicit rap song he posted on YouTube. In the 2011 offseason, Bennett suggested in a radio interview that Jon Kitna deserved to challenge Tony Romo for his quarterback job in an open competition (heaven help the Patriots if Bennett tries anything similar with Brady and Jimmy Garoppolo).

In 2014, the Bears suspended Bennett for five days in training camp after he body-slammed Kyle Fuller to the ground.

And in 2015, Bennett again removed his filter when talking about other players, saying Seahawks tight end Jimmy Graham “can’t block worth [expletive].’’

Again, for as talented as Bennett is, there’s a reason that the Cowboys and Bears dumped him. Bennett also spent one year with the Giants, though it is unclear how hard they tried to re-sign him.

Bill Belichick has been asked just once about Bennett’s personality clashes with his former teams, and his reply back in March was terse.

“Go ask the Bears,’’ Belichick said.

But Bennett claims that no one with the Patriots has asked him to tone down his act.

“When I came here, no one asked me to be anybody else besides myself and I think that’s one of the biggest things — the freedom they give me to be who I am,’’ Bennett said. “When you’re able to be yourself, everyone’s able to see how authentic you are and understand who you are as a person.’’

Bennett did reveal one side of his personality last week — a side that’s vindictive, merciless, and a little petty. It’s a side the Patriots hope Bennett can suppress just long enough to help them win a Super Bowl this season.
