The thing is boxing lost its appeal among sports fans because it was overtly stage managed and corrupt. Jake Paul's entire boxing 'career' so far has been if anything a culmination of those factors. People turned away because it's a circus, and now you've got this extreme version of a circus. I think you can say that sure someone like Jake Paul who can bring a pre-existing fan base into the sport is going to lead to more attention, but really you're just leaning into the WWE-ization of the sport.
Imagine if Jake Paul had decided he wanted to be an NFL or NHL player. He'd try out, get destroyed, told 'good luck', and then muck around minor leagues trying to get better before losing interest because the cameras and money wouldn't be following him. But in pro boxing 'quality' and 'status' have always been a bit of a fugazi, and gimmicks have a much better of working in a sport where there's little oversight, little professional integrity and a heavy mix-up with both show business and organized crime. Jake Paul has successfully blurred the line between boxing as a legitimate athletic endeavor and the world of "Celebrity Boxing". But even if that means there's a new crowd following boxing, it's more symptom of decline than sign of a reversal of it.
