'All' is not accurate in my opinion. I believe practically everyone (not all) perceives Jerry Jones as problematic in how the front office operates month-to-month, season-to-season. I do not believe all or even most observers feel Jones indirectly or even directly influences wins and losses.
Some members have voiced their disagreement that Jones' managerial responsibilities and/or actions carry significant weight in what happens on the field. More than a few have occasionally said he is not even the team's real general manager. Additionally, there remains the contention that Jones does not negatively affect the work environment of his organization intangibly.
I do think some exclusively attribute game-day results primarily to the players and coaches...but not equally to the single individual who put those players and coaches on the field and sidelines. In truth, this is nitpicking, but sometimes an adjective does not mean what it should mean.
