Jake Paul is a joke to the boxing world but he doesn't mind that as long as he earns massive amount of money doing it. This exhibition fight will benefit both of them as Tank Davis will earn more than he used to do when fighting regular boxing fights and he doesn't need to train hard, all he got to do is present and that's it, money in the table for him.
Why he is a joke? Because he is cherry picking his opponents? That is up to his conscience. He was a youtube, an influencer. For me he is sort of a boxing influencer. Dont look on who he fights, look on how much attention and audience (new audience) he brings to boxing. Look on him from perspective of a motivator, an example of what you can achieve if you do something. An average kid becomes a guy who has nice skills in boxing (not a super professional level) and managed to make money out of that. Anyone from local boxing gym could have done the same, but nobody did.
Somehow on some point I understand on why he do that since somehow first he need to pick those fighter that even if they are out of limelight still marketable.
That's why we've seen for many times that their exhibition match events always successful since they pick the right people which can bring them huge profit.
Also no one thought before that he would reach unto this level on which he would fight those past and current champions. At this point this is already huge achievement for his life and its a bonus that he earn huge for those fights he made.
