Tampa Bay Buccaneers tight end Rob Gronkowski's brother, Chris Gronkowski, believes Gronk's NFL future depends primarily on that of quarterback Tom Brady.
In an interview with TMZ Sports, Chris was asked when he believes Rob intends to retire for good:
"I think Rob will play it out until Tom plays it out is what I'm thinking," Chris said.
Chris also expressed his belief that "whatever Tom has left" is what Gronk has left as well, adding: "I just can't see him playing with another quarterback. It's tough to get that chemistry. It's tough to win once you lose that QB.
