After that beating Pac was giving JMM, i doubt JMM will ever be the same again. He was taking a systematic beating against Pac before finding a punch. JMM might be older than Pac, but JMM has had a easier ride opponents wise than Pac, so was the fresher fighter.
So floyd might want JMM. JMM found that punch against Pac as Pac was a little too desperate after being robbed by Bradley.
