I'm not sure anyone of us knows what type of system is used by all the teams, but I wouldn't be shocked to find out that some form of modified PFF system is used. Teams have the advantage of knowing what the assignments of the play are or were, which would inherently make their (the team's) ratings more accurate.
But I have to belief some sort of rating system is used.
