It thus becomes quite impossible to believe in any theory that speaks of "boosting" power in modern times, simply because there has been no such boost . Here's a blow-up graph of the so-called "steroid era", starting at 1982 (because 1981 was strike-shortened and thus not a good data point). Understand that in this graph nothing has been "spliced out" save the single ball juicing of 1993/1994 (whether 1993 was or was not post-juicing is still debated); the numbers on the left would change were earlier splicings and wartime smoothings dropped, but the shape and scale of the graph would be unchanged.
Due to a wide range of media coverage and large scale steroid scandals fans and experts have continued to bring the games integrity into question. Major League Baseball is a game of statistics. The entirety of a player's career is based upon the consistency and credibility of the numbers and accolades acquired during the period in which they played. "Their real impact has been at the margins: There are certainly some scrubs who wouldn't be in the majors without the juice, and we have ample evidence that at the other end of the scale, drugs can take Hall of Famers and all-time greats and help them perform at historically unprecedented levels" (La-Times). When it comes to this topic generally there are two trains of thought. Many do not see the harm with this type of substance use because it makes the game more exciting and allows athletes to reach untested potentials. On the other side of the argument many fans and experts believe the game has lost its purity because of this drug use. More recently an issue has arose with high-caliber players who have tested positive for performance-enhancing drugs are not being voted for on a hall of fame ballot. This fact has brought many to question the game's integrity. No matter the statistics and achievements produced by the certain player prior to drug use, a positive test for steroids has shown to discredit the athletes integrity and career entirely.
Shropshire agrees, noting that in years past, “It wasn’t always clear what constituted getting a competitive advantage and what was unethical or illegal. Good people got caught up in it, not knowing how far was too far.” And, with so much grey area and so little supervision, ethical decisions are made in isolation. Pettitte, the Yankees pitcher, for example, says he stopped taking human-growth hormone because he “just didn’t feel right about it” — not because he was afraid of being caught. A clearly enforced policy would help establish the ethical “bright lines” players need, says Shropshire.
