Re: Best head movement?
I'd say Whitaker and Benitez take top honors. Fluid, natural, well schooled, and in total control. They took evasion to an art form.
Mike Tyson had incredible movement from a technical standpoint, but he still got hit a lot. Most of that had to do with patterns to his angles and bouts of laziness, though. I'd still show clips of him to teach a kid how to get inside.
