Running the ball still matters even if passing is more valuable and efficient.

Being able to do both at a good level opens up your whole playbook and forces the defense to spend way more time gameplanning and adjusting mid game to your offense. A good example of this is Patriots Vs Chargers in the playoffs this year....chargers played safeties at linebackers to counter the ravens run game....then they played the Patriots who decided forced those safeties to shed block after block and they weren't able to.

I'm a big fan of stats and advanced metrics but football can essentially be boiled down to the "styles make fights" phrase imo
