Correct. And a big reason we only put up 12 is because we couldn't move the ball consistently. Yards.
It all ties in, dude. There simply isn't any one stat that is meaningless, only degrees. And when you let teams walk up and down the field on you(yards), your chances of winning plummet hard.
Look at 2017 NE, who went by your strategy. Let the other team get yards, it doesn't matter. The problem is, that might work against crapp teams, teams you prolly would've beat anyway. But, in the playoffs, you are suddenly facing teams that will turn those yards into points. And then not only do those yards matter, they become the most important item. NE not being able to stop PHILLY from walking up and down the field is THE reason NE lost.
Yards matter, possibly more than any other factor.
