I just read the article after looking through the thread over the past few days. This article has no credibility because it has zero balance to it. Of course there are some valid points made about the play of the D, but when you don't give any credit for the successes of the D then it lacks the true view of the D.
On top of that, the writer constantly refers to every player and team by his favorite nickname for them - Tony Homo, the Doncos etc. If you want any article written to be taken even remotely seriously then you have to can the third grade talk.
