Rob Gronkowski isn't sure if he'll return to the Tampa Bay Buccaneers to pursue another championship next season.

"I'm really going to basically do what's best for myself in terms of the football world," the tight end said. "It's going to be a decision based upon of where I'm at in a couple weeks."

Gronkowski came out of retirement to join Tom Brady in Tampa Bay. Brady's playing future is also up in the air.
