arms, too. His fighting style was actually in some key respects closer to Ali than it was to Liston (particularly the head movement as the foundational defensive principle--both were masters).
Tyson & Ali in their respective primes would've been a GREAT fight. A decision would've decidedly gone to Ali, but I think Tyson would've been much more likely to knock Ali out than vice-a-versa.
Ali was very, very special — but Tyson was probably the best pure athlete to EVER fight as a heavyweight. And his training was superb. Ali was well-trained, but much of his skill was of his own genius.
