Right tackle Marcus Gilbert received a +3.2 grade, while right guard David DeCastro nothced a +2.9 on the day, despite an ankle injury that limited him to about 61 percent of the Steelers' offensive snaps (44 of 72).
It was the highest mark Gilbert received in his three-year career.
DeCastro's performance moved him to third in the NFL, behind Philadelphia's Evan Mathis (+25.1) and Louis Vasquez (+13.7). He's nearly four points ahead of fourth-place Daryn Colledge of Arizona (+7.9).
Brett Keisel was the Steelers' highest scorer, earning a +4.5, the highest the defensive end has had since a +4.9 last year against Kansas City.
Mike Adams filled in for a stretch at left tackle when Beachum moved inside, and put up a +1.2 overall, his best grade this season, in 39 snaps. But the rest of the offense failed to score better than +1.0, with David Paulson (-1.9), Kelvin Beachum (-2.8), Heath Miller (-1.5), Le'Veon Bell (-1.1), Guy Whimper (-2.5) and Felix Jones (-1.2) hitting the red.
