I believe Rob Gronkowski’s rumblings about retirement are real. He’s been responsible with his finances (putting away most of his football money and living largely off his endorsement cash), and he’s taken an absolute beating. That this is a real choice for high-profile players now is great progress, too.
While it would be surprising if Gronkowski retired, Breer argues that the "rumblings" are "real." While we expect Gronk to play in 2018, owners should be aware that he is thinking about hanging 'em up.
