Right, that's what they basically do right now in boxing/MMA, exhibition fights with former champions and then see how much money they can make it. Not sure how much guarantee money is for Silva, but I will speculate that it could be in the millions and then Jake Paul taking the lionshare of it. For sure there are still fans that is willing to go to live gate and watch it or buy PPV. So in any case, it's a win win. However, for pure boxing fans, not sure if they will bet on it or want to watch this kind of exhibition matches.
Yes, it's hard to find the excitement for matches like this that's why bettors would just let it pass, I mean for me that will be the case.
It's a money-building thing and just for mere entertainment. Some would want to watch the fight being a long-time fan of Anderson Silva and some scouts also trying to figure out if he still has the power. And maybe, who knows, create something out of it. Turn it into a trend and fix more matches for him even at his age.
Paul should still be careful though as that hands of Silva are packed with a lot of power. If he gets knocked out, he better keep laying on the mat.
