So if PFF is sometimes right and sometimes wrong, does that make them kind of OK? I would argue it makes them unreliable and therefore useless.

Imagine a test for cancer that gets it right 70% of the time. 30% of tests either fail to detect cancer, or detects cancer where there is none. Would we say that it's a pretty helpful tool?

I would say it isn't helpful at all, because even if your test is one of the 70% of times they got it right, you're still wondering whether you can trust it, so it's pretty much never helpful then.

PFF has some weird grading rules too. If an OT completely ignores the DE he is supposed to block, and gives up a sack, and instead incorrectly double teams the DT, PFF calls that a successful block, and does not assign responsibility for the sack to that player. So it may measure how well you block the man you engage with, but it does an extremely poor job of measuring your effectiveness as a player.

Dont forget, PFF tried to tell us Leno was one of the best OTs in the league!

So is PFF ALWAYS wrong? Nope. They are at best random. Which is worse, because if they are always wrong, you can just invert the findings and have usable data - but randomly wrong is like the cancer test above - totally useless.

I always think you throw out their best and worse years and that's who they are which means he should be top 15 at his position. He's going to be fine.

I think Davis is extremely talented. Im not sure if his heart is in it or not though.

Im willing to overlook last year, but Im surprised he hasnt been in training camp much. Then again big guys who are vets often want to skip the summer workouts.

Im gonna look at him with an open mind this year because of his potential, but if he isnt all in, or Jenkins gets injured, we will be really glad to have Bates on the team, and Bates may well beat one of them out for a starting spot on merit alone too.
