The imbecilic false equivalency of the comically ignorant.
The MLB implemented no formal testing policy during that decade. The NBA did. Furthermore, widespread doping in the MLB was not only whistleblown by players like David Wells, but was substantiated when the doors blew open with the BALCO scandal-- the NBA has no equivalent lab scandal underpinning the 80's or 90's. The MLB was slammed with the Mitchell Report in 2007, spanning an investigation that dated back to 2006, which outlined doping abuse by 89 players, many of whom played during the 90's era. This was reinforced by later indepedent reports, including one by the New York Times, naming dozens more players, including those the MLB had learned themselves were doping in tests from 2003 (such as Sammy Sosa). Players like Alex Rodriguez were eventually revealed to have been using steroids as far back as in high school. McGwire and Canseco, two of the most famous home run hitters of that era, later publicly admitted to steroid abuse. That's what "endemic" means. It isn't hidden. PED abuse was so widespread that today Jim Thome is famously celebrated because he was probably the only power hitter of that era who didn't take steroids.
Typical whiny Lebron nuthugger who can't accept that Jordan was a cut above telling himself fairy tales at night to justify his misled admiration.
