Not what I said. His appearance (he got much bigger in his prime years, and then showed up notably smaller the year they started testing for real) and the trajectory of his numbers (he was a 15-20 HR guy for his first 3 years in the league and then blew up in the mid-90s, until he fell off a cliff at the end of his career). Of course, before the steroid era, much of the numbers trajectory would have been considered consistent with the typical prime years for a player in terms of age.
It's obviously all circumstantial, but that's all you need from for many of the paranoid writers out there.
