absolutely. What boxers are masters of these skills? In mma it was prime Anderson Silva and Lyoto Machida.. those two always literally had me on the edge of seat because they were masters of unpredictability. I definitely miss that
Off the top of my head:
Jersey Joe Walcott - master of broken rhythm, never in the same place, threw punches on "off beats"
Willie Pep - one of the most creative fighters ever to lace up the gloves.
Nicolino Locche - danced around the ring. Unhittable. Froze his opponents with feints both with his head and his arms.
Mohammed Ali, nuff said.
Larry Holmes. Crazy underrated heavyweight. Great jab, that he would throw while dancing around his opponent.
Manny Pacquiao - complete fighter including varied timing and feints.
Canelo Alvarez, one of the best feint users in the game.
lomachenko- groomed for boxing from his childhood, his father had him cross train other sports including wrestling, ballet for footwork. Exemplary amateur career. Technical master.
Tyson Fury (when at his best) moves in ways that defy science and gravity. Switch hitter, great jab, head movement, stutter steps and feints.
Lennox Lewis had like 5-7 different jabs, from varied angles and mixed them up, and would also sometimes leave his hand out or strip his opponents front hand down to open a punching lane for his right.
Bernard Hopkins- defensive master, alien, only fighter with a win over father time, crafty.
Pernell "Sweet P" Whittaker - another defensive genius, fight ending power, elite use of angles
Prince Naseem Hamed- switch hitter with dynamite in his left hand. Insane movement which included throwing punches from endless different angles, he would often get his opponent so far off balance that he would wind up beside them or even behind them, where he was in zero danger but he often had clean attack openings.
If I remember I'll come back and post more videos, there is an amazing video I watched recently on Jersey Joe Walcott and how he used his movement and broken rhythm to befuddle his opponents and create opening while avoiding damage in return.
Archie Moore 132 KOs (/TKOs) variety of tactics he could use either outside or in the pocket to create offense for him while he remained safe, even I'm the pocket while using his cross guard defense.
