I really don't want to make this a discussion about PFF but the "I trust my eyes while watching the ball, eating chips and drinking 6 beers" argument is hard to take over 3 professional football analysts paid to watch every individual play using coaches film from multiple angles.
I think everyone here would agree we catch the splash plays right? Simmons played 60+ snaps last night and I bet none of us saw more than 8 of them. He could have been beat in coverage 20 times and just not targeted. He could have been trucked out of position 30 times and we wouldn't notice. PFF also watch all those plays we never see.
