We assume Griffey was clean because he never showed a single one of the hallmark signs for steroid use -- extreme muscle increase, bigger head, acne , etc. Further, most "baseball people" tend to agree that Griffey has a textbook perfect swing for hitting HRs, meaning that he didn't rely on sheer muscle to hit the ball. Griffey's uses flexibility and quick reflexes to generate batspeed, not his triceps. One last thing, Griffey was injured all the time. Guys on the juice don't spend much time on the DL with injuries. Part of what steroids do is cause your body to heal at an extremely fast pace (keep in mind that your body healing itself after a workout is what actually builds muscle). Griffey just never fit the mold of a steroid user. i never saw any huge size difference in alex sanchez or rafael palmeiro. Sure, some guys don't show that many outward signs, but how long were they using before they were caught? Sanchez wasn't around long enough for anybody to know and, IIRC, the Palmeiro incident happened the year before it came out. Probably not enough time to make a huge physical difference in either case. Griffey was hitting HRs at a record pace from almost the minute he set foot in the majors as a skinny kid. If you wanna believe that he was juicing then, fine. It is very hard to believe, to put it mildly, that a guy could have been juicing for 17 years with no unnatural change in his appearance. It's not really all that hard to believe. If you're using in moderation, you can build strength without adding too much bulk. A lot of the guys caught at the major and minor league level have been pitchers, some of whom aren't all that bulky. A lot depends on how you're using and how you're working out. I guess my point was that a lot of those guys haven't been in the majors for 17 years. Plus, Griffey has seen a drop in production over the last seven years. Sort of the opposite of Bonds. I'm not saying Griffey never used steroids or that I would be shocked to find out that he did. I wouldn't be shocked to learn that any player over the last 15 years used steroids. I am just saying that Griffey appears to be one of the least likely guys to have used over that time period when you look at all the information that we have -- that's why lots of people assume Griffey was clean. Some people want to say Griffey juiced because he was a power hitter during the steroid era. It's becoming a witch hunt.
