I was kinda thinking that until the 2nd Marquez fight where Marquez did just as well as when he faced the `one dimensional` Pac in 04. As we know, JMM has never changed his style & if anything was less of a fighter physically due to the age factor in the 2nd meeting. What Pac learned in terms of boxing skills & patience he then lacked in relentless aggression which IMO gave him most of his success while becoming a better boxer. I believe both Pac`s are equally dangerous & effective, its just a bit of a style change.
If you actually take time to read my post rather than just highlighting it then letting rip then you would know that I was comparing Manny Pac to Bruce Lee, not Erik Morales.
