Why are you totally against it?
lol. I would not be against Bill Belichick coming to Dallas.
I do not necessarily criticize Jerry Jones decision making based upon what I would do as GM. I have always criticized Jones' decision making (or in this case hypothetical decision making) because he has a poor history of it that he repeats on a nearly yearly basis.
In my opinion, Belichick wants the same authority he had in New England. I think Belichick was not hired by Atlanta for this reason, despite the public statement released on the matter to the contrary. And if
Arthur Blank is resistant to that hiring condition, Jerral Wayne Jones Sr. sure as
Hell will not sign Belichick.
There may be the possibility of the Jones/Belichick friendship being used as a supportive counterargument. I will ignore it beforehand.
Jones supposedly had a great relationship with Sean Payton. Payton has (or had) a home in the Dallas area. Payton could have easily been the Dallas Cowboy head coach after Jones kicked Mike McCarthy to the curb. He has done worse to a better head coach in the past. And Payton ended up in Denver.
Jones' narcissism will not cede near or full control to anyone. Belichick is an 'anyone' so no I do not see that happening--not while Jones is breathing that is.
Now Jones may come back as a ghost, visit Stephen Jones one day and confess he would have hired Belichick when the opportunity had presented itself while he was living. Anyone is liable to admit anything if they ever managed to escape the Underworld.
