Well, first off. Football Outsiders statistics are actually much more relevant and in depth to actual success. PFF uses lazy statistics and the guy doesn't even know the responsibility of half the players before assigning grades. It's laughable. FO's defensive information is gold, and their offensive stats (which are hard to do for anyone) actually use about as good a system as you can use. Regardless, it was simply a resource to put out the fallacy in your argument, which by you admitting FO was just as BS as PFF, proved my point that your argument is, to be frank... complete doo doo.
Actually we can't sit and debate about the Dolphins OL in run blocking, because you watched 0 games and are using one reference, that you stated, admittedly is just as BS as another resource. My opinion comes from actually watching them perform and run blocking for OL, something you have not done and still feel like you have a right to form an opinion on the subject.
By all means continue, but just know you're a boat adrift, because the wind has been completely taken out of your sails.
