I do think its unfair to say "you can't critique roid users because there's no proof it helps. We've seen statistical proof in the boost during some players careers at times they were found, suspected, or admitted of using. Yes there are some that haven't been league leaders but do we know they'd even be in the league without roids? Also, how much are they taking and what are they trying to accomplish? All those are unknowns.
From everything I've read its (1) very difficult to study the effects of roids on a baseball player, and (2) very little investigation of it has been done. What is suspected is that roids increase bat speed which allows hitters to see the ball longer and also helps recover quicker which helps endure the rigors of the season and heal quicker.
Here's a powerpoint created by someone from Boston College.

Here's an article from the washington post which claims roids do help hitters and can even help pitchers throw harder but it greatly increases the pitchers chance of injury;

While drug experts largely agree that steroids can enhance any hitter's power and likely fueled the unprecedented home run surge in the 1990s, the only evidence to suggest that steroids have significantly affected pitching during the same time period is the injuries that have occurred.

Here's a study by a Tufts physicist which claims;

Tobin reports that a 10 percent increase in muscle mass could help batters who are already exceptional sluggers hit 50 percent more home runs. Earlier studies indicate that such an increase in muscle can be achieved through steroid use.

Here's an article from NY Times health which has numerous physician quotes all detailing how they believe roids can help a baseball player;

Here are some quotes from the NY Time piece;
Quote:
''I've never taken the stuff, but talking to guys who have, they get a lot of extra confidence,'' Mets outfielder Cliff Floyd said. ''They think, 'When I hit the ball, it will go farther than when I hit it before.' They have this different attitude, like they're invincible, and they're just going to crush it. I think that's the real edge.''

''Steroids make your hands faster in that they increase muscle in your forearms and pectorals and numerous muscle sets involved in hitting a baseball,'' said Dr. Charles Yesalis, professor of health and human development at Penn State. ''If you need less time to get around on the ball, you have more time to tell if it's a slider, knuckleball or curve. That makes complete sense.''
Quote:
''It's basic force equals mass times acceleration,'' said Dr. Gary I. Wadler, professor of medicine at New York University, who has spent 20 years studying doping. ''The mass is muscle and the acceleration is the bat speed. There is a collision. The ball is being hit with more force than before and will go farther.''
Quote:
As the player steps out of the batter's box, he does not necessarily have more speed, but he does possess greater explosiveness, because of stronger fast-twitch muscle fibers. When Caminiti admitted to Sports Illustrated in 2002 that he used steroids, he said: ''I'd be running the bases and think, 'Man, I'm fast!' And I had never been fast.''
Wadler said: ''Remember Ben Johnson coming out of the starting blocks in the 100 meters at the 1988 Olympics? It's just like that.''
Quote:
Steroids can assist in the healing process. To strengthen tissue and put more time into rehabilitation, the player will be tempted to begin using again, starting the cycle over.
Steroids help as the years pass, staving off the aging process with more and more muscle. Balls carry farther. Careers extend longer. Numbers reach higher. And the questions grow louder.
