We improved when Jason came in. One part because Wade was really hands off and just said he'd coach the players the team provided for him. The other part, I believe, is because Jason's dad was a long-time scout and Jason had spent a lot of time looking first hand at how a coaching staff and a scouting staff need to shake hands to find and develop players.
We false started early hiring Rob Ryan and his multiples defense that put a ton of pressure on the players to know what to do and manage exceptions. Especially on defense, where you pretty much know you're likely going to need to bring in players at some point and get them up to speed, it was a huge limitation. With the new CBA, we jettisoned that defense and brought in the 4-3 that's pretty elementary in terms of player responsibilities, and put in charge of it a coach who's famous for coaching technique instead of a complicated scheme. That's made it easier for us to be consistently mediocre defensively without really devoting resources to that side of the football. We're deeper than we were, because the player knowledge of the scheme doesn't need to be as complicated and it's just a process of getting the backups where they need to be with the little things.
Offensively, we hit on the OL, and that makes everything else look a lot better. We've done a great job not missing on our 1st round picks, and have found a couple gems in CFA over that time. A lot of it is just having a system in place over time, knowing what sorts of players you need for that system, and then letting the scouts find them. And then having somebody sit on the crazy wild-catting owner to keep him from making mistakes in the name of wheeling and dealing. The success we've been having finding and developing talent has bought some trust there, and we've done a pretty good job filling in the holes. Getting lucky by thoroughly scouting Dak (oddly, our coaches were involved there more than the college scouts, apparently) was the biggest boon that makes everything look different in Dallas this year, but the reality is that the process has been going well for several years now.
