I haven't really seen anyone discuss this, and I myself have somewhat ignored the issue because Arians makes me sick and I wanted him gone even before the 2008 Superbowl win, but I'm curious what others are thinking.
Arians is now 6-2 as the head coach of the Colts, so what the f%#k is going on?
I don't believe that Luck is better than Roethlisberger or that he plays in Arians' system better, so I'll remove the quarterbacks out of the equation. That leaves Tomlin, Arians and the offensive lines of the two teams.
Was Arians an idiot running the offense when he was on the Steelers? That can't even be a question. Of course he was. The question is whether Tomlin, the offensive line of the Steelers, or a combination of the two forced Arians into being an idiot, or is Arians still an idiot and the Colts are just getting very lucky? I haven't really watched them play and I haven't looked at stats to help answer these questions.
