Yes Doctor.
But the rating will not only reflect the number of possesions.
I have noticed many a game where the losing team had fewer or similar number of possessions.
I intend to link the possessions to the actual score scored and also to the quality of the opposition.
Like Richmond beating Bulldogs wouldn't be worth as much as them beating the Lions.
And also plenty of stats against Brisbane but still coming out with a hiding will also be allowed for in the players ratings being downgraded.
