This erratical, now overused term became popular during Floyd's run as 'Money' Mayweather. Since then, a lot of fighters (specifically PBC fighters) have claimed to be the A-side in fights when they either: - Have never done a ppv - Have done a ppv(s), but it does under 500k, (most barely do 300k) - Make 1m or less per fight - Duck top opposition While I'm no fan & I feel he's responsible for the current climate of why fighters think like this, Mayweather earned his way in becoming the 'A-side' (really hate that term) early in his career by fighting the best opposition around. If he had done what these current fighters are doing today - he would only be remembered as a footnote in boxing, and that's they way many of these fighters are heading if they don't step up.
