In fact, if you base an average number of offensive plays in the league (63) on an extrapolation from Derrick Henry's two stud playoff games last year -- in which his total EPA was 2.0 on 34 carries against the Patriots, and 3.5 EPA on 30 carries against the Ravens -- the Titans would be expected to score about 5 and a half points in a game by running the ball 100% of the time. By contrast if the Titans were to pass the ball 100% of the time and perform the way they have so far in the passing game this season, they'd by expected to score 31 points in a game. Now, obviously this is all the land of theory, but it's noteworthy the difference between running and passing efficiency, even with perhaps the best running back in the league. Go ahead and run the ball 100% of the time and see where it gets you. I might be able to beat you with a single touchdown. This is why Belichick's approach was intelligent, and why you don't need an all-world defense to implement it successfully.
