I would hire the Joneses in their current roles.
At the introductory press conference, I would fire them in the opening statement, and say that no one is free from accountability in this organization. I would then work to hire the best GM possible, and let them dictate the on field operation.
I would also look to hire an augmented/virtual reality design team to build a "football flight simulator" to train players at their positions in a virtual setting. Find ways to import playbook data from other teams, and use QC data from down and distance tendencies, formations, blitz packages, etc. to give young players the opportunity to hone their skills in a lab that is as realistic as possible without detracting from the prep time for the veteran starters.
