THE PITTSBURGH STEELERS ARE WHO WE THOUGHT THEY WERE
Just two weeks ago, the Pittsburgh Steelers were flying high at an undefeated 11-0 record. Chatter of them being Super Bowl favorites started heating up given that nine of the 12 teams to go 11-0 in a single season in the Super Bowl era went on to play in that year’s final game. But numerous signs told us that this undefeated Steelers team may be a tad overrated — specifically at quarterback — and their Week 13 and 14 losses to Washington and Buffalo showed as much.
During his team’s 11-game winning streak, Ben Roethlisberger ranked 17th in the NFL in passing grade and the passing offense ranked 20th in percentage of pass plays to generate positive expected points added. This passing offense’s success was predicated on quick throws and yards after the catch — not explosive plays deep downfield. And a relatively easy schedule also helps. That’s not to say they aren’t a great team, but it’s just not a sustainable way to win long-term; they wouldn’t fare well against teams such as the Kansas City Chiefs or Buffalo Bills, whom they lost to Sunday night.
Roethlisberger’s 53.4 passing grade in Week 14 ranked fifth-worst among quarterbacks, and he led the Steelers to the fifth-least efficient passing offense against Buffalo. When targeting past the sticks, Big Ben went 5-of-13 passes for 61 yards with a couple of interceptions en route to a 49.0 passing grade. Half of those passes were deemed inaccurate by PFF’s ball-charting process, and that is no different from what we have seen all season. Among 29 quarterbacks with 100 throws past the sticks this year, Roethlisberger is sixth-to-last in the percentage of uncatchable passes thrown.
Again, the Steelers are a great team, but can Big Ben get them over the hump against the Chiefs or Bills come playoff time? As of now, that seems unlikely.
