You don't publicly snub your boss who simply wants to toast the team's success if you're not trying to get yourself fired.
Jimmy Johnson orchestrated his departure from Dallas. He even said so, i.e., he never liked staying in one place for long.
But he did it this way so Jerry could pay him on his way out the door. If he would have simply said he was tired and wanted to move on, Jerry keeps the money owed Jimmy, especially since Jimmy didn't want to retire for good but wanted to retire to coach a Florida team.
Jerry is an egotistical maniac who meddles too much in football affairs and is the sole reason why the team hasn't sniffed a Super Bowl in 26 years and counting.
But I cannot blame him for firing Jimmy Johnson. Let's stop making him a martyr. Jimmy knew EXACTLY what he was doing.
Having said that, yes, he belongs in the Ring of Honor. I think Jerry will ultimately put him in, but he's going to make Jimmy sweat it out a little while.
