Simplicity of the Dallas Cowboys offensive scheme has to cost Dallas 1-2 games a year.
As you said Belichick would eat Garrett up twice a year if he faced him as if Belichick knows what you are going to do and you won’t change he will prepare his team in a week to beat you.
Dallas doesn’t use misdirection or fake Jet sweeps in their offense. The scheme is nonexistent it’s we are going to do what we do and you gotta stop it.
How Garrett brings back Linehan is amazing. It’s AFC East esque stupid and Philadelphia and NY Giants must love it.
If Dallas was smart they would have tried to kick the tires on John DeFeilippio as a QB coach with the understanding he is Linehan’s replacement but Dallas is just stupid with coaching.
The Dallas talent is good.
Actually, I didn't say Belichick would eat Garrett up twice a year, you did.
Dallas frequently uses misdirection on short pass plays (Gruden's fav spider 2 Y banana) and fake jet sweeps. They're not consistently successful because they tip their hand with personnel (Tavon Austin = jet sweep) or formation.
Linehan is the worst of George Deleone (multiple formations) without the play calling savvy.
I like OCs who frequently repeat effective play calls - make the opposing defense prove they can stop a play that's been executed with consistent success. Deleone sometimes took this too far but he successfully pounded defenses with this philosophy (Norv Turner did too).
Linehan is the opposite. He will have great success running into a specific gap or picking on a DB and he'll stop calling those successful plays to run an idiotic jet sweep with Tavon Austin for a 5 yard loss.
It's compounded by his inability/unwillingness to change strategies in game. If a defense shuts down his strategy (e.g. run to open up the pass) he just starts calling goofy plays like Coach Klein (Waterboy reference for the youngins') without the success.
Edit - Jerry Jones has boxed himself into a Catch 22 with Garrett. He's unlikely to find a great coach who will tolerate his level of involvement so he's forced to keep the Ginger Clapper.
Edit 2 - For all of Jerry's and Ginger's faults they've still won the NFC East multiple times so it's not like Dallas just re-treaded Rich Kotite or Bob McAdoo (i.e. How to Pick an AFC East HC)
