I'm not trying to make Tomlin look better by pointing out Cowher's shortcomings. I'm pointing out that they BOTH have SIMILAR shortcomings. Why is it OK for one guy to have failure, but when the other guy does it, it's much worse?
It was not "okay" for Cowher's teams to lose 4 AFCCG. Recall the old board? The anger and vitriol from those losses would make ISIS freaks shake their heads and say, "Wow, man, calm down."
However, Cowher went to the playoffs 6 straight years after taking over a team that had been the playoffs once in the preceding 5 seasons (1989), and that only after a 9-7 record and an incredible series of events the last weekend to get them into the playoffs. He re-tooled the defense in 2 drafts. He revived a very good running offense.
And he did this with slightly above-average play at QB (O'Donnell), and worse QB play (Tomczak and Stewart).
As Vader has pointed out very convincingly, Cowher also built the team by acquiring players who fit his mold. DL who could fill two gaps and occupy 4 or even 5 offensive lineman; OLB'ers who hunted the QB; defensive backs who were decent in coverage and brutal in stopping the running game; receivers who could block and were tough as nails; very, very, VERY good offensive lineman, not bloated mediocrity in the 2nd round.
Meanwhile, Tomlin took over a team that had been to the playoffs 4 times in the previous 6 seasons, with a franchise QB, an elite S, and coming off a dominant playoff run (beat the #1, #1, #2, and #3 seeds - never happened before or since) just 2 years earlier. He has overseen and been directly responsible, at least in significant part, for poor draft selections, 1st round busts, and players who don't fit the @#$%damn system.
I used to think that TMC was too hard on the Steelers draft choices, since they just did not fit the system. I thought that maybe Ziggy could be a DE, or maybe Timmons could add strength and use his speed on the edge to turn into an OLB'er, or Jarvis Jones would get stronger and turn into a pass rusher ... TMC kept saying, "No, these players just don't fit."
TMC was right. I thought that Tomlin and company had a better idea as to what the hell they were doing than TMC.
I was wrong.
