Mike Vrabel's first offseason as head coach of the New England Patriots is in full swing, as the Pats are well represented at this week's Senior Bowl in Alabama.

Brian Belichick, the son of legendary ex-Patriots coach Bill Belichick, is departing the team after serving as the safeties coach for the past five years, multiple reports said Tuesday, as new head coach Mike Vrabel builds his staff.

Mike Vrabel joined the Patriots as head coach in a throwback to the Bill Belichick era. But his tenure won't involve Belichick's son, Brian.
