Funny how we've apparently had two of them play every game and yet still managed to have the best defensive unit in the league up until today though.
Krul, Coloccini, Saylor, Tiote and Jonas deserve the credit for that.
Simpson's actually played well in the last 3 or 4 games too, actually.
So going by your theory Raylor has gained us +4 points alone, without the help of anyone else.
