Although I cannot comment on the likeness from a first hand perspective (only seen highlighted footage of SRR), I can only go off the experts and their views on SRR. I have never heard the comparison between the two. I have heard the comparisons between Hatton - Duran, but personally I think Hatton is more like Julio Cesar Chavez Hatton's punch is the left hook, to the head, or the body. The amount of KO's by the left make up the majority on his KO list. Again I cant compare the techniques of the hooks, however Hatton's is a brutal tool. Never is slightly unfair. Again with reference to foowork Hatton is quick, light and agile on his feet. His movement to make angles to open up opponents is very impressive. I cant compare either attribute to SRR but both are good in their own rights.
Hatton has both great footwork and a left hook. You look stupid even though you are right to critisize the OP.
Hatton, every boxer has those punches. Its the way Sugar Ray threw them. He could throw something like a double, or triple hook to the head. This is more a flashy move, but Sugar Ray had knocked guys out with the second punch. Sugar Ray had bonafide one punch power with his left hook especially, but he also knocked the **** out of some fighters with his cross. He would utilize both an overhand right and a straight right. He was sort of like, a very accurate, fast, powerful fighter. Was aggressive, but would use a lot of feints.. If he was like Hatton, and Hatton like Sugar Ray. Sugar Ray would have fought Lamotta on the inside in their fights.. Sugar Ray had moments when he would fight inside, a lot of times when he had guys in trouble, he would crowd them, work the body, up to the head. Guys would lean over on him and he would use some nasty uppercuts from both hands. Most of his inside fighting, the stuff you see is from him going for the kill. Everything else, which is most of the fight is setting that kill up. Thing is, he would also knock guys out from mid range a lot with his vintage hooks. For the record. Not saying Hattons style is more similar to Sugar Rays, than Floyds is.. Floyd is a defensive natured fighter who is a counter punching machine. A lot of Sugar Ray's work was offensive, as it was setting punches up with the jab, feinting. I think Sugar Ray Leonard's style was more similar to Sugar Ray Robinson than anyones.
TBH the holding has only appeared recently. The pushing and using his superior weight has always been there, but I have seen more Hatton fights where his pressure has not smothered his own work and there has been limited holding, rather than the 'wrestling' fights that some alude to.
Certainly against Tszyu I think he was very weary of the straight right, and used the tactic to nulify that weapon, the same as perhaps when he fought Phillips. Against Collazo, Hatton was not prepared right, he looked all wrong, and again used the tactic to survive the latter couple of rounds. Against Urango, Hatton was moving round Urango at will initially and whether it was the shots to the body in 5, whether it was the fact Hatton states he had a cold, he certainly ran out of gas down the stretch, and held as a nulifying tactic. The Castillo fight although there was the infamous 'hook and hold' observation on HBO, I thought Hatton work on the inside was great. He landed several fantastic lefts to the body before Castillo went down, and any holding in this fight was coupled with punches being thrown at the same time on the inside. I differentiate this type of holding from the above mentioned holding agaisnt Collazo and Urango.
