While Rob Gronkowski mulls retirement, the New England Patriots may be getting fed up with the star tight end.
ESPN's Jeff Darlington reported on Saturday that sources believe it's "pretty certain" Gronkowski will play football as long as Tom Brady remains with the team. However, that same report includes a tidbit that suggests tension between the five-time Pro Bowler and coach Bill Belichick: "Lingering frustrations remain between Gronkowski and head coach Bill Belichick, along with others in the Patriots organization, according to sources close to each side."
Last season, ESPN's Seth Wickersham reported that there was a power struggle between Brady, Belichick and owner Robert Kraft.
