and amidst all those things, the Steelers are still 8-5. don't forget Juju being out, Pouncey missing 2 games (i think they won both of those. nothing to do with coaching, though, when you lose your starting pro-bowl center)
Wildcat actually was a huge reason that Steelers beat the Bengals the first time they played them, so using it at times has helped and actually worked.
you can nit-pick all you want at some of those other things because that's just in your nature - find ANY mistake that Tomlin makes in the heat of the moment and of course you would have made opposite decision from what he did and it would have worked every time.
doesn't change the fact that he has a team that lost it's HOF QB in the 2nd game, started 0-3, and is now 8-2 since that time and has them with a chance to make the playoffs. find me ONE other team who lost as much as the Steelers have lost this season, especially in regards to the offensive side, and is in the playoff hunt.
