Hmm about Frazier's left hook... I must disagree. He puts in every punch alot of "Body". See him pursuing someone. He bobs down(no no in the modern boxing for reasons that are above my comprehension) and when he goes up he initialise his hook of a perfect position. Second comming from so low gives him alot ot initial velocity thats why his hook are heavy even on long range. Then when he is squared to his oponent it is just beautiful. Not throwing the right hand in this situation is the best solution. What is the best counter for the left hook? Keeping this hand high(or in his case cocked to give an incline target) and play it safe!!! He don't need to be gridy
