Where have I put it all on the personnel. The only thing I have said is that the corners are dogshit. And they were absolutely, with zero doubt about it whatsoever, dog shit.
But I have questioned Shula plenty. I went on about it in a post somewhere around here recently. Have questioned him more than once.
The thing is, though, that only a bad organization would fire a young DC who put up the 10th best defense in scoring with that corner room. What a good organization would do is fix the deficiency on the depth chart and improve the defense, then see how the young DC performs.
