I think he reads d's better and sticks more to what his OC sends in concerning run plays by not audibling. I think the new conservative approach under Rush, ie running more, better suits the defense, field position and special teams identity this team has evolved into.
IF Dak could play conservative and not force pass happy ways as has-been his past behavior, the team can succeed.
I'm not willing to sacrifice wins for a bunch of stats just because the masses want style points, stats and less boring offense.
Now what does Dak do specifically better than Rush?
And no, running is no longer the obvious starting point.
