So.... lets talk about offense and the myth that Butters is doing so much better on offense. The truth is that Butters is doing approximately the same or worse at QB, OL, and TE and approximately the same at RB. WR is the only position with clearly better numbers (probably for obvious reasons IMO given that Chimp disdained the forward pass).
You will also note that Butters increase in offensive talent (19 blue offensive blue chippers vs 15) does not offset the huge dropoff in defensive talent (25 to 9 I think using the original post, I'm not going to double check his work):
Offensive Blue chippers Chimp 15 Butters 19
