Its kind of a shame, because Jason's good at some things that are unique challenges in the Dallas job. And he's good at some of the things that are going to/could help us in the longer term if he stays the course. He struggles with stuff like the game day situations, he's dithered back and forth too much on what he wants to do with the defense, etc. It's definitely hurt us in the short term.
Basically, I think he's weak in some areas that normally aren't as important as the areas where he's really strong, but the team's been crippled in terms of its cap, some bizarre sustained injuries to specific position groups, and he's missed the mark on the defensive secondary/scheme changes that should have bought him time to gradually get us clear of the cap issues and improve through the draft. He's the kind of guy that, if he ever gets on top of the talent problem on the roster, can steer you through anything. But that process of getting control has been too turbulent, and fans have turned on him.
I know not everybody agrees, and that's ok. It's academic if he can't get control of the situation in the first place. But, if he ever does, I do think we've got a guy who can run a team that's good enough and deep enough to make the the coin-toss type question marks pretty much academic for a long, long time.
