Quote:Without knowing chips, pulls, zone steps, etc... it's easy to make mistakes trying to grade guys.  It's why I take PFF with a grain of salt or more.  I don't get the feeling from their writeups that they have good knowledge of (from experience) the interior positions.  Because without knowing the assignments, sometimes you can be lead to the wrong conclusion.

 

A lot of times, a play can be blown up simply because the QB didn't make the right read and get them out of the play.  If a defender crashes down hard enough on a pulling guard, there's nothing good that can happen even if everyone did their job as expected.  Sometimes linemen don't communicate well, expecting each other to take the same guy and no one ending up being on him at all... all because both assumed assignment and neither bothered to check with the other.  There are other times when all you need for a "win" is to get your hat inside the guy.  And other times, you may see a lineman making a pancake at the second level and think it's a great play, right?  Not if he passed his assignment and plowed the wrong guy into the turf, while the guy he should have pancaked just made the play.
