Patriots Coaching Changes:

Tedy Bruschi descibed Mayo as an “old soul.” While a player, Mayo was considered a coach on the field and many of the players called him “Bill Jr.”

Perhaps Belichick’s most difficult season was 2005 when he lost offensive coordinator Charlie Weis and defensive coordinator Romeo Crennel.

The Patriots are hardly in uncharted waters here, the team is quite used to Bill Belichick’s staff being raided during the off-season, and this one like the others, will be handled, mainly from within as has been his modus operandi. But who fills these positions will bear watching.
