In any sport, or anything in life that has a long history, there are going to be positives and negatives—there are going to be high water marks and dark stains. I’m not a defender of PED use and I’m not celebrating the steroid era as a golden age. But it happened and it wasn’t just a handful of players. It was part of Major League Baseball. From a historical perspective, both the good and the bad of the sport should be acknowledged. The rich tapestry of ups and downs, heroes and villains, scandals and rebirths gives baseball a depth unlike any other sport we have in this country. Because of this, writers should leave Hall of Fame voting to on-the-field accomplishments and let their words shape the stories and reputations we pass down to the next generation.
Steroid isolation , depending on context, is the isolation of chemical matter required for chemical structure elucidation, derivitzation or degradation chemistry, biological testing, and other research needs (generally milligrams to grams, but often more  or the isolation of "analytical quantities" of the substance of interest (where the focus is on identifying and quantifying the substance (for example, in biological tissue or fluid). The amount isolated depends on the analytical method, but is generally less than one microgram.  [ page needed ] The methods of isolation to achieve the two scales of product are distinct, but include extraction , precipitation, adsorption , chromatography , and crystallization . In both cases, the isolated substance is purified to chemical homogeneity; combined separation and analytical methods, such as LC-MS , are chosen to be "orthogonal"—achieving their separations based on distinct modes of interaction between substance and isolating matrix—to detect a single species in the pure sample. Structure determination refers to the methods to determine the chemical structure of an isolated pure steroid, using an evolving array of chemical and physical methods which have included NMR and small-molecule crystallography .  : 10–19 Methods of analysis overlap both of the above areas, emphasizing analytical methods to determining if a steroid is present in a mixture and determining its quantity. 
Allan "Bud" Selig's bumbling, fumbling, looks in the other direction and name are all over this scandal as much (or more) than anyone else's. It was on his watch that baseball failed and made it's most embarrassing and longest running ignominy. The NFL took steroids head on in 1986 and has basically brushed every PED incident under the proverbial rug since and no one has paused long enough to yawn. Meanwhile baseball gets slaughtered daily. Heads should have rolled a long time ago and there's only the blood of one that could wash this entire episode clean... Bud Selig needs to pay the price.
