Boxing has the worst sports media
Because literally anyone can go and ask for a credential. Unlike the NBA, NFL and MLB, Boxing isn't truly covered heavily mainstream. NBA, NFL and MLB has heavy restrictions on who can get a credential because honestly they don't need any and everyone.....just reputable reporters, journalists and personalities.
Boxing coverage is primarily handled by youtubers.....Think about it, one of the most prominent boxing voices are Ray Jackson (a dude who drives a forklift and tweets) and Show Biz, a youtuber.
You could literally start a youtube channel tomorrow and probably get just about any boxer to hop on your platform. This sport is just super niche at this point and companies like ESPN only care about the biggest events. Stephen A Smith will cover Tank vs Ryan or whatever big Top Rank fights happen but he's not going to waste his time with Tank beating up a jobber.
