He’s probably Top 25 all time in terms of defensive head movement. However, I think Top 10 would be too much of a stretch at this point, especially with how many fighters in the lower weight classes there have been with excellent head movement over the last 150 years or so of Marquess of Queensberry Rules Boxing.
Nope, there are a lot of slicksters who do it and have done it better with more relentless opponents, also the history of the sport is too rich and diverse to put Cinnamon in every top 10 list under the sun.
Nobody is crying pussyboy. Duran Whitaker Locche Benitez Roy Jones Ali Mayweather Miguel Lora Kalambay Napoles Thats just ten out of the top of my head i could probably name ten more
Mayweather's defense based on footwork and shoulder movement. Canelo just stands in front of you like a statue, and you still can't touch him.
Some more with better head-movement than Canelo... Henry Armstrong Hilario Zapata* Willie Pep Ernesto Marcel Orlando Canizales James Toney Miguel Canto Jersey Joe Walcott John Conteh Harold Johnson Jose Torres Billy Conn Chucho Castillo Lionel Rose Mike Tyson Etc; etc; etc. *Honestly, best ever IMO.
