Of course, but they watch more football than anyone. Their system is a little flawed at times but of all of the analysis out there they are paying the closest attention. That's why it's ludicrous for anyone to dismiss their work because you don't agree with it.
No doubt. Just that you can always find flaws in anyone's analysis because you never really know everything that's going on. I think even the eye test would indicate that TT is not the 7th best QB in the NFL. Some of us want to say that means PFF must be garbage, others might say "I wonder what I missing that leads them to that conclusion?"
