Big Ben and the Stiller Passing Game Guest article, by CK Stiller
Last postseason, Roethlisberger shocked most of the media and football world by coming out and throwing at an elite level in the playoffs. It was in complete contradiction of the reputation he had developed as a "game manager." The Steelers were supposed to be a run first team, and #7 was just an average QB looking great in a QB friendly system. Even now, most pundits will tell you that Roethlisberger is only an above-average QB. He isn't an elite passer in the league of Tom Brady, Peyton Manning, and Carson Palmer. Roethlisberger doesn't have the gaudy 4,000 yards and 30 TDs those guys have. Hell, he only threw the ball 268 times, and averaged just 22 passes per game. Roethlisberger does lead in just about every efficiency stat, such as TD ratio or YPA. Most will simply dismiss this as being a product of the system. I think just about any Steeler fan can tell you the numbers don't reflect the reality of the situation, though. At least, if you only look at the base numbers.
The Steelers run a unique offense right now with Roethlisberger. It's hard to find an actual historical comparison. Those who don't watch the Steelers, may think the team runs a highly conservative offense throughout a game. I mean, they probably wonder how else you would get the Steelers 59/41 run/pass ratio. It's this idea that leads people like SI's Dr. Z, or Micheal Irvin to question the Steelers' ability to keep up in terms of scoring. The Steelers aren't the Broncos. They do not try to hide their QB. This is a misconception. The Steelers end up with the gaudy run totals for one reason only. Unlike other teams, they take the ball out of the air almost completely when a solid lead is established.
Anyone remember Palmer throwing against the Steelers, and nearly blowing the game for his team in the Steelers 38-31 defeat? Or how Peyton Manning was still throwing with a 10 point lead against the Bengals two weeks before that? Doesn't happen with the Stillers. Most of you know that. The Stillers are a far more balanced team early on then most would believe. I would personally argue that the passing game was the driving force behind the offense last season. It was incredibly efficient early. In stark contrast, the Stillers run game struggled early on in games, putting up weak numbers throughout the first half. When one takes a look at the real numbers, the Steelers offense is much more balanced than many believe.
Below are the Steelers run/pass ratios for the first half of games last season with Roethlisberger as the QB. Excluded from the run totals are the few runs by QB's, the results of broken down plays.
First Half Pass/Run Ratio
Week 1 - 9 passes, 15 runs (Titans)
Week 2 - 15 passes, 15 runs (Texans)
Week 3 - 10 passes, 10 runs (Patriots)
Week 5 - 14 passes, 17 runs (Chargers)
Week 7 - 8 passes, 14 runs (Bengals)
Week 8 - 17 passes, 11 runs (Ravens)
Week 12 - 14 passes, 14 runs (Colts)
Week 13 - 20 passes, 16 runs (Bengals)
Week 14 - 12 passes, 14 runs (Bears)
Week 15 - 9 passes, 10 runs (Vikings)
Week 16 - 15 passes, 21 runs (Browns)
Week 17 - 11 passes, 13 runs (Lions)
Total - 154 passes, 170 runs (48% pass, 52% run)
Final regular season totals - 268 passes, 386 runs (41% pass, 59% run)
Playoffs
Bengals - 13 passes, 11 runs
Colts - 19 passes, 12 runs
Broncos - 17 passes, 14 runs
Seahawks - 12 passes, 10 runs
Total - 61 passes, 47 runs (56% pass, 44% run)
Final playoff totals - 95 passes, 123 runs (44% pass, 56% run)
To put this in perspective, here are the total run/pass ratios of offenses considered to be more "pass oriented:"
Total pass/run ratios
Bengals - 538 passes, 459 runs (54% pass, 46% run)
Colts - 517 passes, 465 runs (53% pass, 47% run)
Patriots - 565 passes, 439 runs (56% pass, 44% run)
There's certainly a difference there, but it isn't anywhere near as major as you are led to believe. The run game supposedly drives the Steeler offense, yet of these four offenses, the Steelers had perhaps the weakest first half run game of any of the four teams:
First half run games
Bengals - 214 carries, 956 yards, 4.5 YPC
Colts - 184 carries, 757 yards, 4.1 YPC
Patriots - 186 carries, 671 yards, 3.6 YPC
Steelers - 197 carries, 674 yards, 3.4 YPC
