They obviously contribute, I don;t think anyone anywhere ever said they didn't. The issue was whether or not every time a player has an above average season is it the result of PED's?
And a 1 year aberration does not support the theory of PED use.
When you hear, "oh that guys on ped" for example when Bautista started hitting home runs. Well, that's just people having fun and throwing it out there..I wouldn't take much out of that..
