We are back in a familiar, yet uncomfortable place for major league baseball as spring training arrives. We are again discussing illegal performance enhancers and who did what and when.

Silly was anyone who believed we were in some post-steroidal age these past few years, just as foolishness existed in the way-back machine by anyone thinking BALCO or the Mitchell Report was a grand summation of the drug infestation of the sport rather than just a snapshot.

Thus, it would be just as wrong-headed now to believe Ground Zero for the current scourge is an anti-aging clinic in South Florida run by a fake bio-chemist named Tony Bosch, whose ego, greed and sense of grandeur all appear to far outstrip his medical pedigree.

In other words, this is like finding and killing a cockroach in your home and believing you have eliminated the species from the premises. We should suspect plenty of other Biogenesis-type institutions pockmark the landscape.

Here is the reality: When there is fortune or fame at stake — and not just in sports — many folks will pursue shortcuts, legal and illegal. The idea that there ever will be completely clean practices — on Wall Street, Main Street or on Fields of Dreams — is naïve.

The best an institution such as the major leagues can do is hope greater diligence with testing and — just as vitally — the humiliation that comes when cheaters are exposed works as a deterrent to lower the percentage of usage. The anecdotal evidence the past few years, as offensive numbers have come down considerably, suggests that has occurred.
