You make a compelling case about many of PFF's rankings and I agree with many of them. However, I wasn't addressing that part of your post, I was addressing the part where you said that Bernie was relying on their rankings to make his point. How do you write about a set of rankings without using the rankings? I don't call that relying on them and furthermore, he specifically said you can throw them out completely and made his own case for why the Ram brain trust has not done a great job with the resources at their disposal. I still think you're misreading him in this article.
Here's what I read:
He publishes their rankings for our players.
He goes out of his way with this to say this about thier rankings:
"Of course, this is only PFF's assessment. (Click here to see the chart.) The Rams internally may have different (and better) grades on their players. The same could be said of other independent evaluators — as is always the instance in subjective analyses."
He immediately goes on to say that he disagrees with many of them:
"As much as I respect the crew at Pro Football Focus for their excellent and diligent work, I don't agree with all of their opinions. Two quickie examples: I think defensive endRobertQuinn is an elite player — not a "very good" player. I don't see how QB SamBradford can receive an "average" grade when he's missed the last 25 regular-season games. Bradford hasn't played in a real game since Oct. 20 of the 2013 season. So how do we know? "
He then goes on to analyze what he thinks those rankings say about the Rams personnel.
He adds in many of his own stats, not having to do with their evaluations at all, and comes to some conclusions.
He then ends with his final comments that specifically address your concerns about PFF's rankings:
"You can quibble over these PFF rankings _ or throw them out completely. It doesn't matter to me. But if you put much stock in these independent Pro Football Focus evaluations, then you'd have to conclude that Snead-Fisher have missed a chance to fully exploit the bonanza of draft picks they had at their disposal over the past three years. There's no doubt that Snead-Fisher have upgraded the Rams roster. They just didn't improve it as much as they should have."
Where is the "laziness"?
