The card art has 4 suitcases on it. It has a luggage tag that says TPA (The official airport listing for Tampa Intl Airport). And it says "unfinished business" So.... logically....Brady just recently unretired saying he has unfinished business. Brady isn't getting another card. Everyone thinks this is Gronk but Gronk was pretty clear he doesn't want to unretire again , especially not to Tampa. He seems very happy doing what he's doing now. He alluded to being able to help Brady but only in New England. So yeah, popular thought and on the surface looks like Gronk...however....
Super Bowl XXV was played in TAMPA. Between the Giants and Bills (made me happy being a New Yorker all my life). The game went down to the last kick. Norwood missed a 47 yarder wide right as time expired and the Giants won 20-19. Jim Kelly was the QB. He led the Bills to FOUR straight Super Bowls , including that one, and lost ALL four. Talk about unfinished business...
It may be reaching , but if EA was trying to be cryptic, Jim Kelly is a distinct possiblity
