Ari went from 32nd to 12th in offense.
Ben had his best years with Arians.
Ind was 10th last year under Arians but dropped to 17th this year.
He is easily a Top 5 OC/ offensive mind in the NFL.
They also went from John Skelton/Kevin Kolb/Ryan Lindley/Brian Hoyer to Carson Palmer. Palmer is no prize, but he doesn't suck as horribly as that quartet of crap.
I disagree, I think the Steelers offense has looked better as they've adapted to Haley's scheme. You saw the same issues I brought up about Arians' offense every week while he was the Steelers' OC. Ben just scrambled around, freelanced, and wound up getting killed every season. That's not a viable approach to sustainable success.
Indy's interior offensive line was even worse than ours was, and that's an impressively bad feat. In addition, their new OC didn't understand that no matter how much he wanted to be, they were not a power running team. And Reggie Wayne went down.
I completely disagree. There's a reason the Steelers essentially fired him.
