I cannot stand PED talk, period. However, I have a little different perspective so I'm gonna share this.
I played select/HS ball with and know multiple first (and high) round picks and D1 players. I played in a HS district that has produced many big leaguers and dozens of college players every year. The city of Houston and suburbs are a hotbed for prospects.
You'd be shocked at the number of HS prospects, D1 players, and minor leaguers who take PEDs and don't get caught. A local kid went to school out of state at a very prestigious baseball university, was caught and arrested with a huge amount of steroids. He was providing them to other teammates, was dismissed from the team and is now at a local school. He was the only one who faced discipline. I also have info on several other big time programs where PED usage runs rampant. I've heard so many stories about minor leaguers juicing, and even a current major leaguer juicing (who has never tested positive). I personally know a first and second round pick who have both used PEDs, both never caught.
There are the obvious examples of guys like Brady Anderson and Ken Caminiti who used PEDs and had monster years. However, there are so many more players who use PEDs and don't get scholarships, don't get drafted, and don't make the major leagues. PEDs are not some magical thing that can turn everyone into a stud big leaguer. For every Brady Anderson year, there are hundreds of guys not seeing a spike in performance.
There is no way to quantify the positive or negative impact PEDs have on performance. To make Braun and A-Rod out to be villains just isn't logical when there are so many users not producing monster numbers. All players should be viewed on an equal platform whether they are PED users or not because it is impossible to tell who is and isn't using. PED usage is running rampant at all levels of baseball and no testing policy is going to stop players from using, period.
