I think Arians has more than proven his mettle with Indy last year and having the Cards at 10 wins this season. Haley though, I'm still uncertain about him. The offense is playing much much better now than it did at the beginning of the year but I pretty much put the 0-4 start on 2 factors: 1) young defense not knowing DL's magic & 2) Pouncey gone for the season in game 1.
I think the number one reason of our 0-4 start was that we caught the injury bug early
the two players that impacted us detrimentally through their injuries were RB LeVeon Bell and TE Heath Miller (well and Pouncey, but you said him already, and plus his replacement has been surprisingly great)
Heath Miller was a huge loss, because despite TEs being more prevalent now than ever in the NFL's passing game, Heath has always been Big Ben's number one destination in the Red Zone. plus his back-up, that dude from Minnesota whose name escapes me right now, sucks and is a gigantic fucking pussy
but LeVeon Bell was the biggest loss. in the month of September the Steelers had literally a non-factor going for them in the rushing phase of the game. which was bad news for Big Ben, because teams would either blitz the holy hell out of him, or comfortably play with two extra defensive backs
however, Big Ben has been playing great as of late. also, I'm surprised as to how well Jason Worrilds and Cam Heyward have turned out. also, Troy Polamalu has had a fantastic year breaking his personal record of 5 forced fumbles for the year! Troy's excellent play excites me most, because this means he could have another 3 solid years left in his career!
I honestly doubt we will make the playoffs this year, but at least we ended up respectable, despite our first month of football. I think next year the Steelers will be at least 10-5 and possibly AFC North champs
