Gronk’s agent talks Bucs trade.

New Bucs tight end Rob Gronkowski came out of retirement for one simple reason.

Gronkowski wanted to play with Bucs quarterback Tom Brady.

Gronk’s agent, oily Drew Rosenhaus, appeared on “Late Hits” this evening, co-hosted by Gil Brandt and Alex Marvez heard exclusively on SiriusXM NFL Radio. There, Rosenhaus detailed how the Bucs’ trade for Gronkowski’s rights went down.

And unlike rumors Joe has seen on Twitter, Rosenhaus didn’t indicate that Bucs AC/DC-loving general manager Jason Licht was ordered by Brady to go get Gronk or that Gronk was part of a package deal if the Bucs signed Brady.

But Brady was a key figure, Rosenhaus noted.

“When Tom came to Tampa, that is when Rob was interested in coming back,” Rosenhaus said. “We reached out to New England to let them know Rob was interested in playing with Tom and suggested working out a deal.

“I know that the Patriots organization worked on that with Tampa. I think this was going on for some time based on our contact early on with the Patriots.”

Given Rosenhaus’ timeline, this all began shortly after the Bucs signed Brady. Two weeks ago when Licht was asked about Gronk and the rumors started by a dog, Licht joked that Gronk’s wrestling career was going well and Licht brushed off the question.

In fact, per Rosenhaus, Licht at that time was knee-deep in negotiating the trade with the Patriots.

Gronk has only one year (2020) left on his contract but Rosenhaus made it clear Gronk is very interested in staying with the Bucs as long as Brady is here.

Brady signed a two-year deal with the Bucs last month.

“I think things are going to go really well for [Gronk] in Tampa,” Rosenhaus said. “He’s going to enjoy playing in Tampa obviously with Tom Brady. I think he will be rejuvenated. I am just thinking out loud, I think if everything goes well, Rob might consider sticking around at least for the duration of Brady who has a two-year deal.

“And if Rob is healthy, God willing, and playing the way he is accustomed to playing, perhaps he will play another season or two. He is certainly young enough.

“I am sure [the Bucs] are hopefully he plays for more than one year as well.”

Rosenhaus believes everyone is a winner in this deal — Gronk, Brady, the Bucs, the Patriots and the NFL as a whole.

“It is a big night in the NFL,” Rosenhaus said. “It’s not very often you get a player like Rob Gronkowski to come back and re-enter the NFL and decide he wants to play again. And to see him play with Tom Brady is going to be really thrilling.

“Rob is one of the great characters of the NFL and he will bring a lot of entertainment both on and off the field. Just a great person and he does so much for the sport. It is wonderful to see him healthy again and feeling good about playing again and wanting to play.”

Rosenhaus noted Bucs fans should be geeked about this move.

“I don’t think anyone anticipated Rob playing this year,” Rosenhaus said. “Listen, I am an optimist. I am hopeful at a minimum, he will not only play this year but play out another year since Brady is going to be there. And I think he will enjoy playing for Bruce Arians.

“Rob is excited about going to Tampa for a number of reasons. Tom Brady is one of his best friends. I think everybody knows that. But he is excited about the opportunity to play in Florida. He has a home in Florida. He has a business in Florida and he spent a lot of time training in Florida. This is a really cool opportunity for him. Rob is just pumped.”

And so too is Bucs fandom.
