Oh, I criticize the roster construction under Tomlin as well, as the Steelers have not been able to draft and develop defensive backs to save their lives under him, among other things.
However, the issues with him run deeper.
A team does not get dominated in three consecutive playoff games, two of which they were heavily favored to win, unless there are serious flaws in how the team is being prepared and directed. Sorry, it just doesn't happen.
There is also the issue of the team collapsing at the end of the seasons three straight years now. It strongly reflects teams eventually adjusting to the Steelers and them not be able to counter it.
It's coaching. Plain and simple, and I've just had enough of Tomlin. I just do not understand what rationale can be applied to keeping him around anymore.
The 1980s are widely considered dark times for the Steelers franchise, yet the last 10 years have basically mirrored that in terms of post season success.
