I have no evidence to support this - just a theory.

Obviously a team cannot be superior in every area - not with a salary cap. I have wondered over recent years if the analytics just show that success running does not correlate closely with winning - and our brain trust has decided to optimize the team against the pass at the cost of stopping the run. Because the analytics show that stopping the run effectively does not lead to more wins as much as other competencies. Analytics often uncover trends that run counter to what you eyes tell you watching the game.

In the last two years, have we lost a single game based largely on a failure to stop the run?

On the other hand, I may just be giving our FO too much credit.
