I suggest tempering expectations for the new head coach. Jerry will hire a replacement for Garrett and the first thing to look for is if that coach has the authority to fire and hire his assistants. If the rest of the coaching staff stay and Jerry installs a new puppet head coach, then nothing will change. Maybe you won't have to endure clapping on the sidelines but the atmosphere of the team will not change. It will be a good sign if the next coach starts announcing new hires at offensive and defensive coordinator positions.
We should expect that the next head coach will do a better job managing the clock and asking for replays but unless Jerry gives him control of the players, we will see the same mistakes, the same lack of urgency and the same softness we see today because I do believe that comes from Jerry and the Jones family.
We have said it so many times its not worth saying again, but I will anyway. The Cowboys need Jerry to step back from the team management and operations and let his own newly hired GM and coaches run the team. Let the GM hire the head coach and then let the head coach hire his assistants. But we know this is not going to happen.
