Tysons head movement in his prime is what i think would have been key in ali fight..Mike and Frazier both were tremendous punchers but Mike head movement and speed were better..I give the heart factor to Joe...Lennox and the Klitchkos size is just to immense for these small HW...After cus died so did mikes work ethic...Its IMPOSSIBLE to keep mikes pace with all powet shots and not be in Peek shape..
Hence why he never was the same if he couldn't he guys out of there quick..Cus dying=partying and drugs..Mike was the most ferocious boxer I've ever seen...but his power came at a hefty price in which he couldn't maintain doing dumb shit..
