Really difficult to define because they are so different. Ali was fast and used his footwork to stay outside and at range. Nine times out of ten he was the bigger man and he could dictate the range of engagement with his speed and long arms. Uysk is way different. He is a master at feighting and using angles. Range doesn't really help him because in his era he is the smaller man and staying outside is not a good thing against thr 6'6 to 6'9 monster's of today. If you watch him closely he is at mid range and feighting to get a reaction and then getting in and out with combinations. His movement is not to establish distance but to keep these big guys off balance. Ali and Holmes used footwork ro establish their jabs at range. The Cubans were very similar. Uysk is very different though. He is all about timing, angles and keeping guys off balance.
