Let me clear this up:
Emmitt Smith was the leading rusher 1991-1993, and 1995 and collected 3 Super Bowl Rings, Terrell Davis was the leading rusher in the AFC 1996-1998, leading rusher NFL 1998, and collected 2 Super Bowl rings in that time period. Jim Brown led the league in rushing 1957-1961, 1963-1965, played in 3 championship games, collecting 1 NFL Championship, and never had a losing season finishing 1st in the division 4 times in 9 years.
During the last 10 years only one team that won the Super Bowl did not have the leading rusher in the game and out rushed their opponents. The only time it did not happen, Pete Carroll refused to give a RB nicknamed "Beast Mode" the ball at the 1 yard line to rush for an easy TD that would have won the Super Bowl. Beast Mode rushed for 132 yards in that game.
Finally, Jason Garrett's only double digit winning seasons occurred with the leading rusher in the NFL (Demarco Murray 2014, Elliott 2016, 2018). His record without the leading rusher in the NFL is 5 games below .500.
I do not know why anyone listens to Jerry Jones.
