While Tom Brady wants to continue playing until he's 45, the timeline of how much longer Bill Belichick will remain head coach of the New England Patriots is less certain.

Belichick's friends give him two or three more years, which would be long enough to ensure his two sons, Stephen and Brian, are secure in their jobs as Patriots' assistants.

Belichick even told friends for the past year that he wanted to coach Garoppolo as a starter and he was confident he could win a Super Bowl with him.

The Patriots traded Garoppolo to the 49ers before the deadline, which was a move that surprised people close to Belichick, Tom Brady and Garoppolo.
