I think people over estimate it hurting boxing honestly. Not sure I buy people really following the likes of GGG, Kovalev, Pascal, Ward, Fury etc etc if Manny won. Most likely these aren't boxing fans, just Manny Pacquiao fans and/or Floyd Mayweather haters.
What Al Haymon is doing however, THAT will bring more fans to the sport. Making it accessible with good talent and great matchups with less politics in the way (mostly since its under one promo banner).
*sigh*
Wish folks would use critical thinking a little more when it comes to things like this. We are 48 fights into Mayweather's career, people. You can't possibly be surprised things turned out that way.
And if you're serious about what you consider good boxing, JUST ASK! we can point you to contemporary slugfests and high energy boxers that would show you that the sport is just as exciting as ever.
