It's funny how everyone is OK kicking Belichick to the curb. It was ALLLL Tom Brady. Nevermind BB, had decades of being one of the smartest DCs in the game. He was the reason the Giants won super bowls. Then he gets to the Pats. People act like Brady arrived fully formed as a franchise QB. He wasn't. He was thrust into the lineuup due to injury and was a game manager. They won their first SB with running and screen passes plus defense.
Then Belichick was a smart enough coach to see what he had in Brady and completely redesigned the offense to fit him. The Pats missed the playoffs the year after that first SB win because Brady struggled with the new expanded offense. They kept with it and the next year Brady developed as a franchise QB.
BB also had to deal with losing assistants left and right for head coaching jobs.
Contrast with Tomlin who inherited a SB winning team with a young franchise QB, a great defense and a damn good coaching staff. Somehow nobody in the media ever says Tomlin won because of Ben. Tomlin barely had a resume prior to getting the steeler job. He was a DB coach for a few seasons. He coached a secondary with Hall Of Famers Ronde Barber and John Lynch. Super tough job. He then served as Minnesota DC for 1 year where his defense was last in the league against the pass (or maybe rush, i don't feel like looking it up).
Somehow BB is finished and should be kicked to the curb, but Tomlin is untouchable.
Brady worked within a system… he demanded Arians change his offense to the system he had run all those seasons in NE..
The reason suddenly the NE offense looks like crap has less to do with Brady leaving than with D’s final ly adjusting to that scheme NE ran… why do you really think Brady suddenly looked mortal his last season or why did matt jones go from pro bowl qb as a rookie to benched bum in a season… i mean players can be blamed for not properly executing… but when lots of players are failing the same way, it’s definitely a schematic problem
The NFL is all scheme these days. There are a handful of impact playmakers but mostly talent levels are so even that really it is all coaching and systems… its been trending this way for a long time.
