I don't think I agree that teams should be passing MUCH more as Seth Walder said, but the counter to what Ian is saying here is surely just "yeah, and at that point the numbers would shift and 'the analytics' would call for more runs."
Building off this, if teams started throwing 80+ % of the time, defensive personnel and player archetypes would shift. Along with defensive playcalling.
And you’d see EPA for runs go up and passes go down.
Its much more complex than the raw numbers that exist.
