PFF Influence On You/NFL/Texans

I was thinking about this because Bobby Slowik, a candidate for OC, was at PFF for a couple years. Mike McDaniel mentions it at pressers, not as the gospel, but uses it as a confirmation or other eye for judging performance.

How do you look at PFF grades, if at all? I think it’s a good resource when you know their strengths and weaknesses, can be a good resource, extra element. Will be interesting to hear/see how the influence helped him.
