Ironically, I was about to make a similar thread a week ago.
Roy is right and if you think about any negative remark or knock on a fighter, it originated from a commentator.
I understand that fighters talk down on their opponent but after the fight they give that fighter respect.
However after, and even during the fight commentators like Lampley (main culprit) Merchant and Kellerman do their best to put an asterisk on a fighters win and in turn fans parrot a lot of these ridiculous statements and ideas.
If you ever paid attention, then you would see a huge contrast between guys like Foreman, Lewis and Roy when they called fights as they actually know what it takes to compete and get in the ring.
Even in a loss they can point out what a fighter can do to improve himself and help himself next fight and this in turn makes fans what to see the fighter again.
I'm sure most casual fans listening to HBO guys, not only wouldn't want to see the loser (as he is a bum/overrated) but the champ as well because HBO probably painted the picture that he cherry picked/fought a shot fighter/ fought a guy who was overrated to begin with.
Dana white would never allow that, and that is why UFC is as popular as it is and why most people don't take boxing that serious.
