I'm new to the site and was wondering how to interpret the player offensive system codes A -D. Can't find an explanation on the site.
This is basically just grading the offensive system on how fantasy-friendly it is. So like, the Vikings are going to have a high system grade across the board because Norv Turner's system has been so good for fantasy players for so long.
Another example, Vernon Davis has a C rating because the 49ers system doesn't feature the TE, meanwhile, Carlos Hyde has a B rating because the system emphasizes the running game.
