It was a big part of the reason the Broncos were able to pull out a 31-19 win.
Writer Nathan Jahnke noted the Steelers offensive struggled as a group, but none more than Legursky, who was victimized by Broncos rookie defensive end Derek Wolfe.
Legursky filled in for RG Ramon Foster, who left the game with an eye injury. To his right, tackle Marcus Gilbert went down with a knee injury, and was replaced by Mike Adams (-1.2) who had an up-and-down game in substitute duties.
The Steelers rushed 26 times for 75 yards against Denver.
There was some praise for quarterback Ben Roethlisberger's performance at the end of the first half, when he hit Antonio Brown and Emmanuel Sanders for some big gains. His interception at the end of the game, however, doomed the Steelers, and boosted the grade of cornerback Tracy Porter (3.4).
Steelers CB Keenan Lewis (-4.0), Legursky and Colon scored the lowest for the Steelers in the game.
