This is about the biggest straw man I've ever seen. Tilting at windmills much, Don Quixote?
Arians set the OL back years by bringing in Zeirlein who he later brought to Arizona. Lebeau's defenses are the only reason the Steelers were in Super Bowl contention.
Steelers offenses were 9th, 20th, 12th, 12th, 21st and 22nd best under Arians.
Steelers offenses were 16th, 7th, 4th, 10th and 8th best under Haley.
You want to brag about Arians finishing in the bottom third in scoring 3x with a HOF QB go ahead.
Also, the Rooneys were right not to want Ben taking 50 sacks and 140 hits per year. Arians was getting Ben killed and that's a fact. If Arians hadn't been directly involved in destroying the OL it would be less his fault.
And Tampa ran Brady's offense.
