Which boxers deviated the most with their original style later in their career?

[Mario040481]

Whether people agree or not, JMMarquez was often derided almost in his earliest HBO fights as a much to safety conscious, or boring, counter puncher averse to risk taking, and was still being spoken of in less than thrilled terms, mostly by boxing know-it-all Larry Merchant (surprised, yes?) in his fight against Derrick "Smoke" Gainer, which I think was a title unification at featherweight and his very next fight was the first of the eventual four Pac fights. Because JMM had such a long career, and with the better, bigger, and most entertaining of his fights occurring over that long stretch of time from after Pac 1 until retiring after soundly defeating the bigger, younger, but less skilled Mike Alvarado, and most of them all happening in front of the best (biggest may be the better word, but I am having a bit trouble coming up with a better word) of boxing media, his is a career where it may be easier, than with most other fighters, to almost plot out the changes fight by fight. I think it is pretty much the same as many say of Foreman v2.0, JMM aged in front of us but was always sound enough technically that he was still able to win many of his fights, and even rather handily more often than not. Most agree that the only time he was ever outright, truly dominated in his career was against Mayweather Jr, who was returning from a short retirement, with most seemingly not in any way shocked by this outcome on account of what many thought, immediately after the fight was officially announced, would be just to much of a size advantage for Mayweather, one that was made even much more clearly evident at the weigh in and all the goings down regarding that. Even though thoroughly dominated by Mayweather, JMM again showed the heart and will he displayed in the first Paquiao fight when, although unable to do anything with Mayweather, he never once gave up on trying to win the fight. Before the first Pac fight, many commentators and writers questioned out loud whether that heart, will, and courage, was even anywhere within JMM.
But, with age, and moving up in divisions, Marquez, who was never a Speedy Gonzalez to begin with, was even slower and was often made to trade more often in the pocket due to this and I think it was the always having had such sound technical skills that he never had to depend on winning his matches with athleticism, allowing his career to extend longer than most top tier fighters of his era and divisions were able to. Basically, JMM is a case of an "anti" Roy Jones Jr, who, when the age and whatnot made it plainly visible that he was usually no longer the better athlete in the ring during his fights, the days of, not just winning fights against legit contenders/challengers, but just being competitive in fights with them was looooong over. When a fighter like a JMM begins creeping into the same age related issues, they don't always immediately drop off the face of the boxing world as they often show strong abilities to adapt and incorporate different techniques and strategy to try and supplement what it is they no longer can do as well as they once previously could. They become the very dangerous, and the real "wily veterans" of boxing

The Marciano never had to change. The man was a fast learner.

- -Keep it short and sweet.

Manny dominated with 5 hard KDs in the first 2 that coulda been stopped. PreBALCO Juan ducked the immediate lucrative rematch to fly to indonesia where he further shamed hisself vs John for a piffle $25k minus expenses for his overseas team flown over.

Anyone not recognizing this small slice of his career ain't playing with a full deck.
