Yes we could be a high octane passing offense all of the time, but if the defense knows this, they will eventually find a way to stop it.
You can blame Arians, but we do have a pretty good ground game, and it eats the clock. Coaches need to mix it up. If they don't most teams will solve your puzzle rather quickly. BTW, I don't count any of Brady's* stats, because he is a cheater. It's easier to complete passes if you know what the defense is doing before the play.
I agree Arians should go no huddle shotgun 4 and 5 receiver sets more often, but we still have to grind it to win, IMO.
