Last month, former New England Patriots coach Bill Belichick shockingly accepted a job as the head coach at the University of North Carolina, leaving his NFL past behind for the college game where he'll coach for the first time in his career.

Bill Belichick has a simple way out of the North Carolina contract as NFL teams reach out about a potential return to coaching.

Belichick famously spurned the New York Jets after he was named Bill Parcells’s successor. His tenure lasted less than 24 hours after he wrote his resignation on a napkin and jumped ship to take over the New England Patriots. This move paid off handsomely.
