Also, need I mention that, if Bill comes to Dallas, either he will have to agree to having Jerry down on the field looking over him at all times, telling him how to run the show, or Jerry will have to agree to just be an owner, sit up in the owner's box, and let Bill and his coaching staff actually coach the team.
The above can also be said about Jim.
Sadly, it can also be said about any other head coaching candidate out there.
