Williams will reunite with coach Mike Vrabel in New England after working on Vrabel's staff for six years with the Titans.

The Detroit Lions lost offensive coordinator Ben Johnson to the Chicago Bears this week, and are bracing to lose defensive coordinator Aaron Glenn to a head coaching gig as well.

New England Patriots coach Mike Vrabel is expected to bring a couple of more familiar faces on his newest coaching venture. According to ESPN’s Mike Reiss, Frank Piraino and John Streicher, Vrabel’s former strength coach and football research director with the Tennessee Titans, could be joining him in New England.
