And if I'm not mistaken, before the video is going out in the public, for sure they have shown this to MP, or Sean Gibbons as the President of MP and he should agree or not agree with the video and requested that Tapales deserves exposure as well.
Although both are champions, I understand that the video is all about Inoue showcasing how great he is.
Tapales's camp should not feel bad about it. In my opinion, it's the right way to market the fight, considering Inoue's popularity compared to Tapales, who has just recently made a name in boxing. Given that the fight is taking place in Japan, the target audience is the Japanese market, and the promo video aims to convince more people that their hero is unbeatable. These are just promotional tactics, however, and they do not dictate the outcome of the fight. Tapales should continue with his rigorous training and aim to win. If he manages to upset the champion, it would be a huge success for him, and the effective promotion would likely result in a decent amount of earnings.
