You can't take away from Jerry's accomplishments as a business man, he's done an incredible job building the Cowboys brand and promoting his team. But he's a fucking moron when it comes to anything football and if you think otherwise you're as much of a dumbass. _
Half of those 10 playoffs appearances and that SB title came from Johnson's team, still had that OL, the QB, the WRs the RB up until the turn of the century. Now I'll give the man credit for anything post 2000 as he didn't have Aikman or Emmitt and was doing it with Quincy Carter amongst others.
Jerry Jones's teams have been garbage. Not sure how closely you've been paying attention, but ever since Stephen Jones started playing a major role in player acquisition, that is when the Cowboys started competing again. That team always takes a step back when Jerry wakes up from whatever pill binge he's been going through and starts talking mad shit in the media, but make no mistake, he's the worst thing to happen to a team with immensely deep pockets.
