For me it proved a number of things here is a list of ten.
Conor McGregor could have made a good boxer if he had dedicated his life to boxing instead of MMA.
Floyd Mayweather is a genius. The Best Ever when it comes to selling a negative fighting style that many boxing fans hate to watch but they still watch it anyway.
Casual fight fans hold the money in boxing and MMA.
People are stupid. How many times do we read people moaning about the PPV prices just don’t buy the shit.
Financially boxing still kills UFC.
A good boxer will (nearly) always beat a good mix martial artist in a boxing match.
The same as above but vice versa.
Money Talks
Two great fighters can fight an ugly and messy fight. There styles clashed horribly.
People always believe the hype.
