I've seen some chatter on this forum and others regarding the Steelers pass/run ratio in Denver. Some argue that Ben threw too much and the Steelers should have tried to run more. There are two problems with that argument.
One, stubborn and predictable running plays called early on in the game put the Steelers offense in 3rd & long situations, meaning Ben had to throw to bail out the offense. He went 11/15 on 3rd downs. Essentially, the Steelers were too unbalanced in favor of the run in their first few offensive series of the game.
Second, no-huddle in the second half. Both teams offenses went up-tempo in the second half. This is mainly because the Steelers and Broncos were trading leads. When you're behind, you're going to throw more.
The Broncos offense ended up being more balanced than the Steelers offense. Know why? The Broncos were playing in 2012 and not 1972. They allowed Manning to throw early in the game and mixed in running plays. They did that the entire game, even when they went into the no-huddle and it kept the entire Steeler defense off-balance.
The Steelers on the other hand were playing in 1972. They stubbornly tried to pound the rock on first and second downs, only to find themselves in 3rd & long situations. They did nothing to mix things up early on. The Steelers think they have to establish a running game before Ben and the receivers can do anything. The Steelers need to take a page out of the Broncos book. Let Ben throw more often earlier in the game, mixing in running plays to keep the other team's defense off balance and set up play-action. Perhaps then instead of needed him to make a comeback drive in the last 3 minutes, the Steelers would be milking the clock with the running game. Besides, the talent on the offensive side of the ball suggested their strength is passing and not running (even with Mendenhall back).
Steelers fans often blasted Arians for being predictable in the passing game. Being predictable in the running game is no better, and does nothing to protect Ben by putting him in a 3rd & long situation. In the end, the pass/run ratio isn't as important as it once was. The rules in today's NFL favor passing, so likely the numbers will be skewed in that direction anyways.
