New England Patriots tight end Rob Gronkowski did not commit to returning to the team in 2018 in the wake of Super Bowl LII. This could have been the result of a question catching him off guard while he was still thinking about the game, but there is enough smoke from various channels to suggest that Gronkowski is legitimately thinking about his future.
Gronkowski is financially secure for the future, has had a Hall of Fame caliber career, and has battled through numerous injuries that could naturally lead him to questioning whether he should put his body through another season of stress.
