A lot of what you have written is based on hearsay and assertions. I'm not claiming it to be wrong but in reality we were not privy to what was said and done behind closed doors. E.g. the strong rumours were that Jerry Jones wanted to draft Johnny Manziel. If this was actually true or not - who actually knows for certain. But if he did, then he clearly did not love Tony Romo as much as you have claimed throughout this thread because he wouldn't draft a QB high in the first round to replace him with juice still left in the tank.
What we do know is that Jerry Jones is the owner, president and General Manager of the Dallas Cowboys.
It again, goes without saying that, if he wanted Tony Romo to come back in for the team in 2016 then that would have been done. The last time Jerry had a Head Coach who made his own decisions was Jimmy Johnson and it took him what 25 years to admit his mistake in sacking him. The fact that he rolled with a rookie QB in 2016 was the beginning of the end.
