The way I look at it is that,for example,Michael Voss is out this week.
So with Voss out,and say,Corrie in,one would think such a major change in the team lineup could possibly mean a decrease of about 3 goals or so,as many think that Voss is a 3 goal better player than Corrie.
I figure that the total score would in fact only decrease by about 4 points.
All the possessions that Voss was going to get don't just disappear.They are in fact going to be shared by other players.
And that is how my ratings of Michael Voss of 8.2 compares to Anthony Corrie at 4.2
Not that Voss is a 4 point better player than Corrie,but in the overall team plan he is!
