Of course there is a correlation between the passing game and the running game, it would be ridiculous to assume tjete isn't.
What is the whole point behind "play action"? The defense has been successfully run on so they are more weary of the run. The quarterback fake hand off is effective precisely because the run is effective. This split second hesitancy is the vital element in creating seperation necessary for long completions.
In 2014 only one team passed less. Although the Cowboys were ranked #31 in attempts, they were #16 in yardage.
And then everyone knows the all familiar attempts stat associated with Romo, he win 75% of the games when he throws less than 35 times, 40% of the time when he throws more.
Each season Tony Romo has 6 to 10 games a season where he threw 35 or more passes. In 2014 he had 2.
Obviously, when he isnt passing , the Cowboys are running, that's an elementary correlation.
This is a norm for the entire NFL. Teams that pass more than 55% have a combined losing record. Teams that throw less than 52% have a combined winning record.
The entire "pick your poisen" scenario featured by the elite offenses in history was predicated upon the correlation between the run and pass as it pertained to opposing defenses. Key on the pass, we run. Key on the run, we pass.
