Well I agree that his article was not balanced. It is very close to the couple of posts I put in the post game thread but as has already been pointed out, addresses everything like it is a total negative without even mentioning the other side of the story.
However by the same token, as has already been pointed out here on many occasions, many Pats defenders especially in the secondary have regressed with time, not improved. So claiming that some of these guys will be the cornerstone to some great defense at some point in the future would seem to ignore what we have already seen several times repeated.
There are IMO simply not enough guys on the field for this defense with the physical talent to play in a league that has made so many rules changes favoring offense in recent years. You can see it in the way they react on the field, they way they move on the field. They have some qualities however that makes some of them effective against the run for example. Some of the qualities that make them effective against the run also makes them effective at jarring the ball loose from guys causing turnovers, that is if they are in position to make a hit in the first place. Some can hit but can't tackle. Some can neither hit nor tackle. The base defense overplays the run to avoid being carved up by it which along with some other flaws that relate to pass defense, means it ends up giving up miles of passing yards...still though that is the right decision to make "most of the time" for the defense that they have.
So it is not all one way as that article suggests....hardly all one way. But that does not change that fact that this defense is short on talent. That appeared to be the basic premise for the article and in that sense the article is correct. IMO it is more correct than some assumption that these guys are the future cornerstone of some future great defense. How much into the future do you want to look for one? How long do you think the average player stays in the league before the meat grinder chews him up and spits him out?
