Nothing undermines the credibility of the sweet science more.
For instance, say a novice fight fan watches a fight like the recent Tapia-Ayala rematch. Casual fans don't really care about the soap opera of the promoters, the venality of the alphabets or the chaos that is the state of modern boxing. In every era, if you examine the records, there have been ten to twenty fighters that would have been champions or top contenders in any decade of the last century. All the fighters the Bucket lists are at or very near their primes. This disqualifies fighters like, Leg-Iron Mike, Evander Holyfield, Bernard Hopkins or Pernell Whitaker who are on the downside of their careers.
