After the Rizen win in Japan by Mirko im sure he retired with a good sensation, he demonstrated he could still kick ass.
He should retire now, im sure he is a multi millionaire, all he needs to do now is open a couple gyms and enjoy the unlimited passive income.
Same goes for Silva, his days in the UFC as a world champion are over.
I have no idea about Aldo vs Holloway, that's one I can't predict.
Im saving some money for the Mayweather vs McGregor fight, that's going to be huge. I don't see how you cant lose if you bet for a Mayweather win. It worked 49 times.
The hype when Mirko joined the UFC was so huge that time. But losses to many unknown fighters that time stop the hype train, too bad. As for Silva, nothing to proved anymore. He is already a legend and please don't fight and enjoy your life.
As for Mayweather's record. "49 have tried and 49 have failed".
Still having a hard time picking Aldo vs Holloway? You are not the one. I still don't know who to pick with.
