Or in this case that was about as long as Shades had much of Cowher’s players and staff.
OC - Bruce Arians > Matt Canada
TE - James Daniel > Alfredo Roberts
DC - Dick LeBeau >>>>>>> Teryl Austin
LB - Keith Butler > Denzel Martin and Aaron Curry
DB - Ray Horton > Grady Brown
There wasn't much carryover, but look at the guys who stuck.
Bruce Arians is a very good offensive mind and would've been here longer if his scheme didn't get QBs beat up and hurt. He obviously became a good head coach.
Dick LeBeau is a legendary defensive coordinator. A true innovator and one of the best of all time.
Keith Butler was a legit DC candidate.
Ray Horton eventually became a DC for three different teams and head coach for the Pittsburgh Maulers.
Even Cowher's 2005 coaching staff:
Whisenhunt - future HC
Grimm - good OL coach
Whipple - quality QB coach, college HC
Hoak - long-time RB, excellent work
Arians - WR coach, unreal
Daniel - long-time TE coach
LeBeau - we know how good he was
Mitchell - excellent DL coach
Butler - good LB coach, worthy DC
Perry - so-so
Horton - future DC
Spencer - meh, but ST coach was always a battle with Cowher
That was a excellent coaching staff with a mix of long-time assistants who exceled in their role or up-and-coming coaches who eventually were promoted.
