Guys in massively popular sports with constant commercial exposure actually face consequences by the brain trust, sponsors, officials and more so in their bank account. Boxers get a slap on the wrist, more often title shots and lets face it, boxing has always been the red headed step child in the bigger sports world. The McQuire and Sosa duel and chasing records of 'Americana' legends surpassed the game at times. It was literally all over the place daily. Also power hitters like Bonds and Clemens are on a more personal stage with fans. The entire at-bat for a DH and deep ball threat is a prolonged mind game, drawn out theater in the game. As a former big follower of the game, baseball nerds LOVE to keep and track stats that start soaring! And in fairness Holyfield never 'failed' a test either .
