Boxing isn't moving forward with technology. We have the ability to check a replay to see if, say, Whyte's fist or head knocked down Parker. One bad call can completely change the fight, and then the fans are normally shown a replay during the break which clearly shows what happened but the guys fighting are sol.
I'm all for the legitimate regional titles to help move up the ranks and fight for the big titles but I feel the most obvious issue in boxing is to many world titles and other silly unnecessary titles in each division at the top,that does nothing but add confusion to who the best is. The other problem imo is the whole scoring system which is outdated and flawed,unfortunately I don't see it being changed anytime soon so they can at least put in properly trained and independently assigned judges and officials for title fights and other important fights.
Having more than one heavyweight champion, there obviously should only be one belt. The fact that you had Charles Martin as the heavyweight champion of the world, when everyone knew he was rubbish, and there was far superior heavyweights out there, just makes boxing look like a complete joke.
The WBA especially is taking the **** with there obvious money grab with there different level world champs with sometimes 3 different champs with the whole "super","regular" as well as interim champions LOL
The inconsistency in the testing programs lists of banned substances and the levels of what is acceptable, allowing there to be a difference between in and out of camp, the credibility of any excuses used to explain an adverse finding, the willingness to gain an advantage using substances and finding loopholes to excuse cheating. The dumbest thing about boxing is the amount of people at every level willing to sell their souls for money, the lack of any voice from within the sport wanting real change.
Your comment "Amateur boxing is a sport, professional boxing is a business." is spot on. In the pro game, PEDs, corrupt judges, fouling, rehydration clauses, catchweights and manufactured titles are all OK if it makes business sense. It's the business of prize fighting masquerading as a sport. If we thought about it, we could come up with a sizable list of hot shot amateurs who never made it in the pros. For most of these guys, it makes sense to let them adapt to the pros before throwing them in with the big dogs of their division. The exceptions are guys like Loma and Usyk who spent so many years in the amateurs they dont have time for the careful approach. They have no choice but to move quickly.
Head gear isn't a big deal, but the gloves are and as you mentioned the length of the fights. But as you pointed out, probably the single biggest difference is in the amateurs the focus is on improving and getting better while gaining experience against different styles and fighters. Professional boxing matches are straight dog fights with guys trying to hurt, damage, and decapitate their opponents. That's the biggest difference right there.
The camera angles are ridiculous. I can't stand the interviews of the coaches during the fight. Don't need to hear a conversation while trying to watch.
If the scores were revealed, would the fighters know or just the viewers? If a fighter knows he's up 4 rounds with 2 to go, he can run the rest of the fight. I think it's more important to get the scoring right, than knowing what the score is after every round.
