I didn't like the hire when it was made. I assumed it was Jerry hiring someone he felt he could control and pay on the cheap.
That said, I like what I've seen so far. From a culture standpoint, Schotty brings a lot of energy and connects with his players well, but I've seen instances of Schotty also being willing to hold them accountable or challenge them on something. I can understand some people viewing Schotty as a try hard, but I think he's being genuine. And judging by what the players say about him, it seems he is managing to create a balance between having fun but working hard.
I also think he's brought something to the offense it has needed for a long time. Across both the Garrett and McCarthy years, I read a lot of comments from defensive players around the league saying how predictable the Cowboys offense was based on personnel and formation and how they knew the play was going to be a run or pass. Listening to Greg Olsen last year, he said under Schotty, the offense is now wedding the run and pass well, meaning they're able to either run or pass out of each look, so they're not telegraphing their intentions pre-snap. Schotty also got more pre-snap motion and misdirection incorporated, which was nice to see.
I thought the offense did a better job last season sustaining drives more consistently when the game was still competitive versus in previous seasons when it seemed the offense was more sporadic in doing so and they got a lot of their yardage once they were a few scores behind and the opponents' D was playing semi-prevent.
I don't know whether he ultimately succeeds or fails, but I think he brings more capabilities to the job than I first assumed.
