Yep Dinamita needs to retire on a high note 100%. There is nothing else to prove and he will never be able to top this win or performance. If I was him I would not let Arum sucker him into Pac/JMM 5. JMM needs to retire and enjoy his life and walk off into the sunset and the HOF. That was a KO that boxers try for during an entire career.
Dinamita is the MAN!!!!!
