Jimmy Johnson – Dallas Cowboys

Like Pete Carroll earlier, Jimmy Johnson might be higher on this list if not for one setback. Unlike Carroll, his setback wasn’t play calling, it was management. Johnson won two Super Bowls with Dallas, but never got the respect he desired from team owner Jerry Jones.

Their constant disagreements ultimately ended with a “mutual parting of ways.” Johnson was the head coach of Dallas for four years and won two Super Bowls by a combined 52 points. If he and Jones could have made nice with each other, who knows how many more rings he’d have.
