Tom Brady was worried about his job. And was tired of his boss.
Those are some everyday problems for one of the NFL's all-time greats, but it was reality for Brady the past few seasons and coming off New England's Super Bowl loss. The quarterback has spent his entire NFL career with Bill Belichick, and has spent plenty of time wondering if and when it's time for a change.
That's according to ESPN's Ian O'Connor, author of a new book, "Belichick: The Making of the Greatest Football Coach of All Time."
"If you're married 18 years to a grouchy person who gets under your skin and never compliments you, after a while you want to divorce him," a source told O'Connor.
