'Greatest 2-Yard Run in NFL History': Remembering Cowboys RB Marion Barber

The tenacious Dallas back broke seven tackles - including five in the end zone - to avoid a safety against New England in 2007.

But the greatness of the author of one of the most iconic, tenacious runs in NFL history, who died suddenly Tuesday in Frisco?

The Cowboys released a statement confirming the tragedy: "We are heartbroken by the tragic death of Marion Barber III.

Marion was an old-school, hard-nosed football player who ran with the will to win every down.

He had a passion for the game and love for his coaches and teammates.

Our hearts go out to Marion’s family and friends during this difficult time.''

Said former coach Parcells: “He was almost like a perfect player.''

Said former coach Garrett: "He would run through the wall for you and he always had your back!

I absolutely love Marion Barber and will miss him very much!''
