Rob Gronkowski can’t even post a comment on Instagram without stirring up controversy.

With wide receiver Danny Amendola expected to head to the AFC East rival Dolphins, the Patriots’ All-Pro tight end shared a special message Wednesday to his soon-to-be former teammate.

“It was a honor playing with ya the past 5 years @dannyamendola Thanks for all the hugs and memories!” Gronkowski, 28, wrote. “Stay lit, Be FREE, Be HAPPY. Your hard work, the way you play at your size, the pain you fought through, the hits you take and get right back up talking s–t back. I appreciated it all. Congrats. Enjoy Miami kid.”

Amendola, 32, is expected to sign a two-year, $12 million deal with the Dolphins, which includes $8.25 million guaranteed.

After posting the tribute, quarterback Tom Brady chimed in, writing, “Well said gronk !!!!”

While many Patriots fans are mourning the loss of Amendola — a playoff hero this past season — to free agency, others are speculating about Gronkowski’s curious capitalizations in the caption, particularly, “Be FREE, Be HAPPY.”

Is it another hint at some Patriots palace intrigue?

Gronkowski reportedly considered stepping away from the game last summer, dissatisfied with the cultural climate in New England. And this offseason the retirement rumors are here after his Super Bowl LII press conference, in which he would not commit to returning next season.

“He didn’t enjoy himself in 2017,” NBC Sports Boston’s Tom E. Curran said in February, via NESN.com. “[Gronkowski] did not have a good time despite the fact his body was in a better situation than it’s been in a long time — ever maybe. Despite the fact that he’s one of the most dominant players at any skill position, it’s starting to wear on him physically, mentally, the atmosphere in New England.”

There has been significant alleged discord in New England, from Tom Brady and Bill Belichick friction to complaints about Belichick’s controlled culture. ESPN detailed the cracks of the Patriot Way in December, highlighting an apparent power struggle within the organization.

Brady, Belichick and owner Robert Kraft have since publicly denied a rift.

As for Gronkowski, he’s putting the future into his own hands.
