After the Justice Department stripped JR and Bobby from using the Ewing name, where they had to accept a deal to avoid prison. This after Cliff Barnes gets 10 percent of Ewing Oil. I’m on season 11 and I haven’t watched Dallas in a very long time, but I believe Cliff becomes president of Ewing Oil. They all talk about how much Jock meant to them. They, particularly his sons, used to put him on a very high pedestal. Jock would have been utterly ashamed of them IMO. I’ll even go one step further. JR, in particular, was supposed to be a very smart oil man. Was he, may I say, overrated? He seemed to suffer a lot of major loses in the later seasons.
