That's an opinion and speculation. There has been plenty of proof through history that Jones was an issue concerning Johnson.
It's s
peculation that Johnson wanted South Florida? Seriously? Johnson not only wanted South Florida he specifically wanted to take over for Don Shula. There were times when he would actually let slip the words "my fins" in 1995 while he was working for Fox and Shula was still coaching!
Whatever his personal opinion of Jones, Jimmy never, ever had trouble getting Jerry to do exactly what he wanted. Jones provided rubber stamp approval for everything Jimmy requested.
if Jones was owner of the Dolphins instead of the Cowboys I'm sure Jimmy would have made do.
The one thing they disagreed publicly about in Dallas was Johnson's availability for coaching interviews. Jones denied the Jags request to interview Johnson, and it pissed Jimmy off. He replied through the media that he at least wanted to see the offer.
Jimmy knew Jerry was never going to let him leave Dallas, so he made it happen.
