it sometimes can, and it worked for vernon. but it wouldnt and wont work on pbf, not that this is a prime example but corrales was big and had long arms and he was destroyed, but the main reason why just bieng tall and jabbing floyd wont work is his elusive style and defence its terribly hard to break it and its awesome for counter punching especially for the left hand (jabs included) cos his left hand is low when attacking and high when defensive but his right arm always stays in a shell like position at the body like a trap for you to throw a shot and he rolls his shoulder up and he leans well to and he counters brilliantly i mean im not the biggest fan of floyd , but theres no doubt his techniques are sound. but i dont really see margarito as much of a fine fighter with his jab not like dlh, and its not that pbf wont fight him due to fear its that floyd thinks hes a bum and that hes fought nobody decent and he doesnt see him as a big opponent worth a big fight , thats assuming of course word hasnt got round as it seems to be the hottest topic. but margarito is more hype than genuine skill.
