Grading players is so subjective. Otherwise drafting players and signing free agents would be fool proof. Well it is not.
NFL Teams with professional scouts, coaches and talent evaluators get it wrong half of the time. PFF has to be less than that. So I am not going hold PFF grades as anything more than a not professional grade and more of an opinion of a nonprofessional.
There are certain stats like sacks that artificially elevate a players score when they can have serious weakness’ in their game. Trent Murphy or Preston Smith are the perfect example.
Alex Smith played on a great KC team that had a decent offensive line, great running game and talent all over the roster. They won a lot but never went far in the playoffs. Alex got a big contract on a banner stats year. But with us last year the team won with him but his passing game was not great to say the least. It wasn’t his talent, it was the talent around him was less. How do grade that PFF stat boy?
