I could see Frazier to Chicago when/if Nagy is finally let go, for reasons mentioned above: connection to the Bears as a member of that 85 team.
Plus the chance to work with a young, dynamic QB with a high ceiling who is a bit raw and needs some time. Sound familair?
I could see Frazier trying the same formula there: strong defense, weapons for the QB and a disciplined tight locker room.
WAY easier in Chicago than Las Vegas, where you have Mark Davis hanging around.
