When you coach for 49 seasons, it's destined that you will coach against either a former staff member or even a former player of yours.
That will be the case on Saturday when the UNC football program travels to take on UCF.
The Knights are led by Scott Frost, who is in the first year of his second goaround leading the program. Before he became a coach, Frost spent some time playing in the NFL, as his playing career started with three seasons in East Rutherford competing for the New York Jets from 1998-2000.
Frost's time with the Jets overlapped with Belichick's, as the later was the team's defensive coordinator for two of those three seasons Frost played as a Jet.
