being able to throw large numbers of powerful, accurate punches is a huge asset. guys like hopkins, who are incredible when they can control the pace, are troubled when someone is throwing at a high rate. as long as it's not just throwing for the sake of throwing, it has it's advantages
Zab is a stupid fighter, but has a naturally larger frame than pac, and has fought at SW I believe. I think pac is just too small for pbf, who will come into a pac fight weighing the same he did against JMM, at least 152. A mismatch.
The only thing Khan has going for him, is a cherry-picking trainer who will protect his glass chin by match-making him against shot fighters... just like what Roach did with Pacquiao so his limited skills weren't exposed again.
Pacquaio never used to be smart, but he is very much so now, his ring senses have increased unbeblievably
Look at any fight with a boxer with fast hands and throws lots of shots, most people are used to the old 1-2 but many just cover up when a guy keeps throwing because they aren't used to it.
