I saw it, and as a die-hard Steeler fan, it made me physically sick. But to be honest, I think the entire loss was Cowher's fault. He is the one who gave Maddox the starting nod in the first place (in spite of the collective groan coming from Allegheny county); then, after Maddox showed that he didn't have command of the offense, Coach Cowher kept him at the helm despite having a more capable back-up in Charlie Batch. I'm not even going to touch the fact that Bettis was not used at all in the 2nd half, as that speaks for itself.
People wonder how the Stillers can have, year in and year out, one of the most talented teams in the league, and yet fail to win the big ones. I think the Jacksonville game showed why.
