A lot of fans who complained about the Arians offense did so because it didn't resemble the offense of the early 70's. I thought the Arians offense was good in between the 20's. Where it was weak was in red zones. Too many field goals when there should have been touchdowns. Had there been more TDs then I don't think Art would have been able to fire Arians.
BA got a lot of crap for letting Ben do his thing. But I think he got it that it just has to be that way to be successful. Everything I've heard this year points to Haley starting to get it too.
