Wikipedia:Articles for deletion/List of lineal boxing world champions
First, WP's goal is to report what others document as notable, not to be the "goto place" to settle arguments between sources.  I would also dispute that there's enough significant, independent coverage to show  is met.  You have 4 articles by Jake Donovan, which WP would recognize as 1 source and all of the other sources are from organizations with vested interests in the topic.  I'm not seeing anything that would make me think the AfD on CBZ lineal champions was incorrect or has been superseded by a better article
