The Denver Broncos used a powerful running game to defeat the Oakland Raiders Sunday. The Broncos racked up 299 yards on the ground, with 163 of them coming from running back Willis McGahee. Quarterback Tim Tebow also had a 100-yard day, running for 118 yards, as Tebow and McGahee became the just the fifth quarterback-running back duo in NFL history to each run for 100 yards in the same game.

But while McGahee and Tebow accumulated the stats, Executive Vice President of Football Operations John Elway said that the real praise goes to the offensive line. On ‘Elway Live‘ Tuesday, Elway told Broncos TV’s Chris Hall that all the success on offense, including with the running game, starts with the big boys up front.

“I think anytime you’re successful on the offensive side it’s all tied to the offensive line,” Elway said. “Those guys are really the unsung heroes and most games are won in the trenches. They did a tremendous job on a very good defensive line. It opened those holes and Tim and Willis took it from there and got the yardage in the secondary.”

Elway said that the offensive line went into Sunday’s game with a chip on their shoulder, due to their performance in the Broncos Week 1 matchup against Oakland. In that game, Denver rushed for a season-low 38 yards while the quarterback was sacked five times.
