What are some other over their prime fighters that changed their style to offset age

Hopkins. B-Hop was much more agressive and appiled alot of pressure in his younger days and was more of a savvy counter-puncher is his later career. oh yeah. Completely forgot about Popkins

Most recently I'd say a big one was Shane Mosley. Shane adjusted pretty damn well for a guy his age fighting more flat footed as opposed to a more explosive fluid boxer that he used to be. He used to have one hit ko power but threw combinations in bunches with decent defensive awareness. He adjusted as he got older and sat down more on his punches and used flurries and what little explosiveness he had left only when the opportunity presented itself. I'm sure having an ATG chin helps... Even Floyd seems different, he's much less of a mover now than he used to be. He's completely stationary at times his last few fights. Marco Antonio Barrera also become a more technical boxer later in his career. After the Morales fights he had toned it down some. Then after the Pacquiao fight it was even more noticeable. Barrera was a better technician than he gets credit for since JMM seems to dominate all the credit there.

If you guys remember, early on in Juan Manuel Marquez career he was known as a "boring" and difficult fighter. It's actually been a while since JMM leg's have been shot. If you notice he doesn't move around like he use to (obviously due to age) and now he uses his boxing intelligence and lays traps for his opponents. He's taking on a more aggressive approach because of that and it's making him more fan friendly. Has any other boxers in the past changed up their style due to not longer being the same fighter and doing it successfully? Hopkins. B-Hop was much more agressive and appiled alot of pressure in his younger days and was more of a savvy counter-puncher is his later career.
