Brady admits it might be Belichick who ultimately pulls plug.
"I'm still working hard, doing my job, because that's what he's looking for," Brady told Jarrett Bell of USAToday.com. "And the day that's not what he's looking for, there comes a time for everybody. I hope to make that decision hard on him for a very, very long time."
The history on Belichick is telling. As coach of the Cleveland Browns way back when, he didn't shy away from cutting quarterback Bernie Kosar, a wildly unpopular move that generated a meltdown among fans. He later traded away Drew Bledsoe to make way for Brady in New England, and he's done the same with aging players on both sides of the ball ever since.
All of this is a ways off, but Brady knows his coach well enough to forecast how this ultimately might play out.
