I think the issue is that we have made mistakes in getting the "right" talent via the draft.
This team has always built with the draft. But it only works when you draft well.
We have always avoided a lot of big splash free agent moves but when you miss in the draft you have to adjust.
It is hard to judge the coaching philosophy when the talent is weak.
Nevertheless, to the extent that Tomlin has responsibility for selecting the talent he does bear accountability.
