This is boxing, not a fight where Silva won a championship. Anderson Silva is already 47 years old, I don't think he can keep up with Jake Paul who are still young and active as a boxer, if this is UFC, then I might bet on Anderson, but hey, it's boxing.
Maybe Jake Paul is trying to keep his undefeated record and will never fight a boxer that could potentially give his record a 1L.
Jake Paul isn't an elite fighter though. He is just young and active. He is not the kind of boxer who is well experienced and have fought elite fighters. Even if Anderson is washed up, his advantage would be the experience. Yeah boxing and UFC is a different combat sport. You'll probably exhaust yourself faster in boxing than in UFC. Keeping up against Jake Paul won't gonna be a huge problem for Anderson. He can do that, but it could potentially make the fight boring.
However, I don't see any huge advantages in either of them.
I guess this is why fight fans is going to buy the tickets, Paul isn't elite but Anderson has experience but no longer in his prime. And probably fans are going to watch because they think that Anderson has the chance to knock out the arrogant Jake Paul. As for boxing vs UFC, I'm a fan of both. So this is going to be a different experience for Anderson although he has beaten JCC already inside the ring. But Jake Paul wanted to continue his hype so let's see and hopefully this fight is not going to be stage or rig.
