To save boxing you need the one thing that there is 0 hope of in boxing; a promoter/org that is willing to spend money to develop young talent without any hope of a return on investment for several years or more. Boxing needs a Bonnar/Griffin type moment and it needs to be free on TV for people to watch. Watching two up and comers fight is a hell of a lot more interesting when you actually know something about the two fighters. There are no young boxers that I am aware of that have people talking. There is just the same few names that get tossed around and repeated.
Also, boxing cards need quality undercards. When I used to watch the big name PPVs for boxing, it was always a social event/hang around/do other things until the main event came on. No one really got hyped other than the top fight and rarely was the relevance of any undercard match known.
Lastly, less time with the announcers talking! I'm tired of seeing that old dinosaur talking about boxing. Show some fights, show some KOs, show something! Especially with a large group of people watching, no one can hear him. Show prelim fights or something. Show the next guy fighting winning his last few fights. Something visual for those at the bar watching.
