WTF are you on about? Calzaghe was the aggressor and Calzaghe was the only one interested in trying to box. Hopkins just ran away and tried to cheat his way to victory and got found out.
Ok, being the aggressor ISN'T a punch, or a skill, its called, taking a step forward, can you do that, can anyone? yes, the boxing skill comes in for instance, when Calzaghe comes forward in a burst of short weak inaccurate punches and through that Hopkins picks out a accurate single counter punch that has power and lands cleanly. Thats skill, rushing forwards with brawl style tactics isn't actually a skill, its called brawling, and its not good boxing. If that fight had gone on for 20 rounds Calzaghe's face would be black and blue, with cuts all over, and Hopkins would have been tired, without a scratch on his face laughing as he knocks out Calzaghe.
AS for holding, I'm sorry but watch the fight ffs, all the early rounds its mostly Calzaghe holding. he was rushing forwards and getting caught by heavy counters and holding on to stop being countered. For every hold in the fight where you can see Hopkins hooking his arms around Calzaghe there was another instance where Calzaghe was holding Hopkins. You can physically see this if you rewatch it. IF Calzaghe has his arm hooked around HOpkins at any point he's holding.
IN general all boxers hold these days, way more than they should and its a shame, but a commonly used tactic. But very often even when one person holds, the other is too. Frequently you can see both hopkins and Calzaghe hooking their arms around each other as neither seemed to want to fight close. Calzaghe wasn't getting any good punches in close so held, and Hopkins was tired and didn't want to waste effort on short small punches, but save his strength for the power counters which he threw all night long.
"The Ten Point Must System
Each judge scores each round using the following criteria:
* Clean Punching (25%)
* Effective Aggression (25%)
* Ring Generalship (25%)
* Defense (25%)
Clean punches are above the waist, on the front or sides of the body or head, and with the knuckle of the glove. The judge must determine if one boxer is landing more clean punches than the other.
Effective Aggression means landing punches while moving forward. If a fighter is aggressive but not landing punches, that does not count as effective aggression.
Ring Generalship means who is controlling the action in the ring, using strategy and skills beyond straight punching power. Is one fighter using agility and feinting to throw his opponent off guard? Or setting up his opponent for effective combinations? When one fighter moves the other around the ring at will, that fighter is displaying ring generalship.
Defense refers to a fighter's success at avoiding blows. This can be accomplished by blocking, bobbing, weaving, good footwork, and/or good movement.
Each of these criteria is supposed to be given equal weight (25%), although there's some dispute as to whether that actually happens. "
When you make "slapping" contact or tap the opponent it DOESN'T COUNT. THe contact is supposed to be good clean contact which counts as the knuckle area of the glove making clean and "flush" contact with the opponent, this is something Calzaghe did NOT do. Hopkins barely took a hard punch, Calzaghe took many, HOpkins should take the whole 25% for defence. He didn't take a tough hit till the 8th round, JOe took repeated hard rights throughout the entire fight.
Aggression, sure joe should it, but it was pointless, he wasn't making good clean contact, aggression without good clean contact doesn't count, so none of his did. Ring Generalship, Hopkins got off all the best punches, Joe kept moving forwards but had nothing to show for it.
THe days of "clean contact" mattering are gone. Tap the opponent and it counts. THe rules here are the ones that used to matter, and are supposed to be the rules still but are completely ignored. Frankly Calzaghe barely had any rounds where he made decent punches, and HOpkins had loads, he should have won. Anyone that thinks otherwise doesn't know the rules of boxing, and is one of those ridiculous english fans who think their guy won because he's english.
Its just a shame judges have given in to the pressure of fans who don't know a thing about boxing and now give decisions the way the fans want rather than by the rules. Boxing will most likely continue going downhill, with lots of fast and frantic and completely helpless fighters winning all the fights.
The judges are best to judge not arm chair supporters like ourselves. The statistics and the judges showed that Joe won the fight so suck it up.
