All I know as a former ballplayer is that Jack Clark had a perfect baseball swing, and Pujols has a typical juicers swing. The no stride all upper body swing is the first clue on who the juicers are. I will one up Clark. A very high up Yankee official told me that a certain reliever about to retire was suspected to be a steroid user from the time they brought him up from the minors. The same guy later told me that David Wright could only get the bat speed he generated with a little help from PEDs. Another good story, a friend of mine worked in the Mets organization for Steve Phillips, who is now on Sat radio. After Piazza did not get into HOF, Phillips blasted everyone who implied that Piazza was a juicer. Anyhow, my friend told me back when Piazza was on the Mets that he was without a doubt a heavy juicer. His source, Steve Phillips.
Look what the juice did to Nomar up in Boston. Stuff ruined his body & career.
