Who is the greatest of all time? Mike Tyson or Muhammad Ali?. Tyson became the youngest heavyweight champion of all time in 1986 at age 20. Tyson fought behind a high guard in the peek-a-boo defence style. He would lunge in with hooks which often knocked his opponents out very early on. Tyson had a great chin and a huge neck to absorb punches, he had great head movement, great power and great speed, he was very aggressive and could cut off the ring very well. When Ali Was in his prime he had amazing footwork, against London and Williams he was Barely hit and could also punish his opponents at will. Ali also had amazingly fast hands, faster than Tyson, Patterson and any other heavyweight we have even seen. Perhaps and underrated part of Ali’s offensive anrsenal was his power, Ali did have a lot more power than many though. So who's the greatest? draw your own conclusions. By ReznickProductions.
