Doesn’t mean those guys aren’t juicing for speed getting around on the ball.
People are always surprised when the scrawny, marginal players get caught, but they’d likely not be in the league without the boost.
You may be right, but there have been lots of scrawny guys who could get around on the ball who played during times when steroid use wasn’t common in anything except body building. And, they were also batting against guys who could throw 90+ MPH.
That said you are absolutely correct that the ranks of MLB have had a lot of players in recent years who have clearly been juicing, including many of its biggest stars. Sad.
