It's a really hard topic to write about. He had a hand in developing two great QBs in Manning and Rothlesberger. He has helped hold the team together in the wake of Pagano's illness. He is a really likeable guy. That being said, it is not hard to see why he was run out of town in Pittsburgh.
He seems to find a way to self destruct a game as often as he finds a great play to call. His performance in the Titans game was beyond bad today. He continues to telegraph run plays out of the power formation for no gains and losses. He insists on a vertical pass game with no line to protect his QB. He continues to push for below average players to play over those who outplay them (Seth Olson anyone?). His game plan has been a disaster as it has resulted in his QB struggling to complete 50 percentage of his passes and a not so great turnover ratio.
He has to set Luck up to be more successfull. That means running different plays out of the same looks. Don't spread it on pass plays and run out of power formations all the time. Give him so bootlegs, some draws, some short passes to keep the third downs manageable. Luck has really bailed Arians out this year on third down and late in games. Tailor the game plan to what you have to work with. Get the TEs involved more. You spent a 2nd and 3rd pick on two TEs you hardly use.
Arians looks like a failure as an OC when you look at what Seattle, Miami, and Washington have done to help their QBs. If it wasn't for the success the team is having, people would be calling for his head. He needs to be more flexible in what he wants to do and this team would have a lot easier time moving the ball and winning games. I don't want to completely rail on a guy when we are winning, but the more I watch this team the more I think we are winning in spite of him.
