Yes we also remember half were as cheap as they come and his mates kept kicking it to him.
Do u think he was drug free that game ?
Are you implying
a) Cousins didn't play well that game
and
b) He only played well because he was on drugs?
Despite the fact you contradict yourself, that argument is totally flawed.
Of course he played well. 38 possessions and we saw him running as hard as he usually does both ways. If I recall correctly he also had the most contested possessions in that game.
Your second point is as equally stupid. At that point he was cleared of having any drugs his system. Even if he had, I highly doubt the drugs he took would've enhanced performance.
