I posted that video yesterday and I think the best response was that it looks like bad Madden AI that play alone seems to run contrary to Mustiphers high pass block grade, but it also looks very typical of his play in general I'll be honest, I've lost a little bit of respect for PFF's Oline grading after Michigan was given a mediocre run block rating after running for over 400 yards on Penn State. In fact Penn State had a considerably higher run block rating in the game despite rushing for 300+ less yards. Now I get it, the point of grading is to try to rate performance beyond the ultimate result so you will occasionally see grades that don't jive with what actually happened but man the results plus the eye test really didn't match up to what the grades were.
