Was Luis Gonzalez juiced when he hit 57 HR's and 142 RBI's in 2001? He never came close to that again or

He is one of many that you can make a case for, Brady Anderson did the same type of thing. Tino Martinez never really matched his 50+ in another season but did have quite a few of more power than those two guys. It is all speculation anyway...unless there is real proof (Brady looks more guily than Gonzo, he blew up in one season, his numbers and body both blew up and he crashed quickly after that.) you can not really call it into question.
