How different/better the offense becomes ultimately falls on Ben. I think across the board most are assuming Haley > Arians. None of that matters if Ben doesn't evolve with the changes.
I've seen plenty of times where underneath routes are wide open yet Ben still takes a sack while looking downfield.
I believe that's where BA's abilities end, and Haley's pick up - just by the nature of how he's handled similar situations in the past.
I don't think anybody expects Todd Haley to pull a Bruce and stand there with his thumb up his ass chewing his cud if he does his job, puts his receivers in place to receive, and sees Ben consistently "take a sack while looking downfield."
Quite the contrary in fact, as his detractors here have frequently lamented.
And I think that Todd Haley's penchant for being publicly and immediately vocal will make a huge difference in helping
Ben tweak his game...
...like we all say he needs to anyway...
If you've ever coached, mentored, parented, whatever, and were faced with helping to address the behavioral concerns of someone you had stewardship over, you already know that such concerns are best addressed immediately and clearly.
We have no Idea what BA said to Ben later in the week after a game.
My take is that by waiting to address any concerns he might have had with Ben's play, the effectiveness of any corrective coaching would have been significantly dampened.
Likewise, the more severe the concern, the less of an impact a coach could have by waiting to address it.
Never said Haley needs to go all Bobby Knight on Ben.
I've only ever asked that Ben have the benefit of a coach instead of a buddy when doing his job.
With his golf buddy gone hopefully those days are behind us.
I expect more from a coach, and that's where Todd Haley will stand head and shoulders over Bruce Arians...
