Re: Could Ali handle the size of a Lewis?
The size of Lewis is not an issue. Ali took on guys that were as big height wise, and I'm a firm believer that there is no such thing as universally good weight at heavyweight, there's only what is good for the individual. Two guys can be the same size and weight with one being solid muscle, and the other being soft.
Lewis would present problems to Ali due to his jab, versatility, (ability to box, ability to go out in seek and destroy mode and punch) and ring IQ. And prime Ali's handspeed, mobility and accurate punching would pose serious problems for Lewis, and I think Lewis would have a tough time pinning Ali down.
It's similar with the Klitschkos, except I think Ali has an easier time with them than with Lewis.
