Three days into the NFL offseason and Rob Gronkowski already has an offer to become a porn star.

The website issued a press release this week that presents Gronkowski the chance to "act" in one of its films. And is prepared to fork over some serious cash to make the scene happen. According to the press release, the website will match Gronkowski's base 2014 salary if he agrees to do the movie. That's a whopping $3.75 million for one scene.

"There is no question that Rob Gronkowski has what it takes to make an excellent male performer in today's adult industry," the press release says. "He has proven both on and off the field that he has the body and the attitude to be a hugely popular male adult star."

The offer is for him to do a scene with porn star Bibi Jones, with whom Gronkowski is quite familiar already as photos such as the one above were posted online last year.
