Not to be a debbie downer, but the only fix would be Jerry dying.
This team has done everything. Change coaches, change schemes, change players etc. Same old mediocracy year in year out.
Bottom line is we are just a fundamentally flawed organization who's leadership cares more about marketing the brand and letting everyone know he's the face of the team than he does delivering a structured, organized, consistant winner.
I think an offensive scheme change could really help.
The defense was bad in the 2nd half but through the entirety of the season thus far they have been much better than how they finished last year.
Romo has had like 10 games outside of a Garrett system. Back in 2006 when he took over for Bledsoe. Since then, Garrett has been the only person who he has worked under.
Garrett's system is fucking broken. They don't scheme to get players favorable match ups. They want to be a 2TE unit but when the opportunity presented itself for Gavin to do just about the one thing he can be counted on to do (be bigger than whoever is guarding him and outjump that player), Gavin wasn't even on the field. How in the fuck do you let that even be a possibility? Split him out wide on one side and Dez on the other, whoever is getting singled should have the look.
There is no quick fix but getting a real offensive coach who has complete command and knows the fuck he is doing would really help the offense.
This team has underperformed on offense for far too long under Jason Garrett.
If they don't pick their shit up, he has to go.
