A change at head coach usually means more changes below him.
For the Bengals, the hiring of head coach Zac Taylor has resulted in the arrival of 15 new assistant coaches, who have collectively worked with four different NFL teams; most of them just a season ago.
Those coaches, in turn, could bring in new free agents.
Brian Callahan, Lou Anarumo, and Mark Duffner could bring in players from the teams they just left themselves. LB coach Tem Lukabu is coming from Mississippi State, but is not far removed from a stint with the 49ers.
