Actually they do improve your quick twitch muscle movements which is why sprinters are faster, baseball players hit the ball farther and throw it harder, and so on. They wouldn't have been so prevalent in the Olympics if they only affected pure strength. What use do swimmers have for pure strength? I'm not sure how this myth that steroids don't help baseball players first got started, but it's completely untrue. They won't help you hit a ball, but they will help you hit it farther. Just like they wouldn't help a pitcher locate a pitch, but they will help him throw it harder. I think the most likely scenario would be that if Braun is guilty he was taking something to stay healthy. That's a good point, but the talent still has to be there. I could take juice and it will help hit the ball harder, but it won't make a good player. Steroids certainly make a difference. Those triples turn into HR's, doubles into triples, singles into doubles, etc. But you still have to know how to hit in order for steroids to make a difference. Clean Bonds already knew how to hit, Roid Bonds turned those hits into HR's.
