Wade had full-control over how practices were run.
I could have my dates mixed up, but I believe in January 2013 I was playing golf with a very famous former Cowboy that was a teammate of Garrett's. He had been to many Cowboys practices under Wade and then under Garrett as HC.
The main point he made about Wade was that Wade was far more interested in having guys watch film instead of practice on the field. He would allot a certain amount of time for field practice and if the team looked bad, they would try to run things again, but once that time was up...they were going into the film room and study.
He told me that Garrett was more into practicing on the field and execution. Having the players drilled and drilled on technique by the coaching staff. And he would keep them on the field until the execution and techniques were being done the right way and they can worry about game film later.
He told me that Garrett's approach makes players better from his experience because all the game film in the world won't help if you can't execute yourself.
So Wade may not have had any control over the offense, but the way he ran practice dictates a player's progression regardless of what side of the ball they are on.
I'm not a Garrett fan anymore. I think he has too many weaknesses. However, I will give him his due...he does a pretty good job at developing talent.
To me, he has to make the playoffs this year or he should be canned. I don't think this team is loaded with talent, but there is certainly enough talent here for this team to make the playoffs with a good coach if they stay healthy. And if they can't stay healthy, this is the 4th year in a row where the team couldn't stay healthy and it's apparent that he does not understand how to coach a team and prevent the players from having nagging injuries (1 year is nothing, 2 years is a bad luck, 3 years is a trend, 4 years is a fact).
The positive I believe is that we have enough talent and well-developed talent that a new coach would have a good opportunity to succeed.
