I was thinking more about the 80's teams with Montana, but the Niners sole SB under Steve Young happened for one reason, and one reason only. Jerry Jones decided he knew more about football than Jimmy Johnson and ran him out of Dallas, replacing him with Barry Switzer, who managed to win a Super Bowl in spite of himself (Bill Cowher completely outcoached him in the '96 Super Bowl, and if it weren't for Neil O'Donnell throwing interceptions left and right, Pittsburgh would have won that game), simply because those Cowboy teams of the early-mid 90's were so loaded.
