Five losing seasons in a 19 year coaching career. Three of those he lost his starting QB for the majority of the season.
Not saying he's Andy Reid or Bill Belichick but they wouldn't be who they are either without Patrick Mahomes or Tom Brady (or Donovan McNabb).
I think he was good, but isn't adapting very much as a coach. As a division rival fan, I absolutely loved the hire when Dallas made it.
I guess I am just not sure what you mean by "adapting". He develops star players, his coaches get hired away and he puts top five offenses on the field on a regular basis. What kind of adapting should he be doing?
As for developing players:
As QB coach for 5 years with the Chiefs, his QBs were Bono, Grbac, and Gannon.
As O-coord for 5 years with the Saints, the starting QB the whole time was Aaron Brooks.
As HC for 13 years with the Packers, he had Rodgers the entire time. I'm not sure he 'developed' Rodgers, but maybe he did.
As for his coaches getting hired right away:
This one confused me.
He had 6 OC's under him in Green Bay. None are Head Coaches. (The ones with the most success after leaving him were Philbin and Hackett... lol)
He had 2 OC's under him in Dallas. Neither of them are Head Coaches.
I feel he's an old school head coach stuck in his ways, and not in the same tier as Harbaugh/Reid/Bill. His playoff record in Dallas was 1-3... with 2 of those 3 losses being at home as favourites. Wasn't a good hire by Dallas, and I can't see teams falling over themselves trying to hire him now.
You seem dead set against this guy. He consistently wins, consistently gets top play from his QBs, consistently puts top offenses on the field (and no shortage of top defenses too).
McCarthy coached GB for three seasons before Rodgers got his shot. He coached him for 13 seasons. It it fair to say he had a positive impact on Rodgers development. It isn't a maybe, it's a yes.
Regarding other QBs: New Orleans was his OC job in the NFL and he coached Brooks, a limited QB at best, to his five best seasons. Brooks was notably worse after McCarthy left and was out of the league within two years, at age 30.
I don't know what to say about Grbac, Bono and Gannon not thriving with him as the QB coach. Any success and failures have to trickle up through noted offensive geniuses Paul Hackett and Marty Schottenheimer. Bono's best year happened to coincide (and it could easily be conicidence) with McCarthy's first year as QB coach. Grbac and Gannon each started 16 games over two seasons in KC after Bono. And Gannon played well enough to parlay that stint into the starting QB job in Oakland. These aren't major McCarthy accomplishments but you can't simply point to Bono/Grbac/Gannon and say "See, he did nothing." Because that doesn't tell the story at all.
McCarthy has had coordinators and position coaches hired from his staff to bigger jobs. Their subsequent successes and failures have no bearing on McCarthy. McCarthy run teams made them look good enough to get opportunities, that's the relevant factor. Joe Phibin was hired from his staff to be a HC. Ben McAdoo to the Giants. Dan Quinn to the Commanders (hiring the right guys is part of being a HC, you can't ignore it just because he coached defense). Patrick Graham was hired away from his staff as LB coach to become DC in Miami.
And Nathaniel Hackett wasn't on McCarthy's staff in GB.
What is "old school" about him? You want to tell me Mike Tomlin is "old school" and I'm on board with you but McCarthy? Does he not play the analytics game well enough? Please explain it.
