if you could have only 1 trait - this would be the first to ask. but it isn't everything. add chin + size - you become something special.
its a big factor but it's not everything. Remember ALi Vs Foreman? who's stronger ? and (but) who won ?
Man ur so wrong jezz people , hand speed, punching power, chin and the ability to endure punishment are natrual assets , and can not be thought u ether have it or u don't, but they are not needed to be great fighter. If that were the case any bum with hard punch would be champ. the best asset any fighter can have is his wit and the abilty to over come his opponent assets , what ever it may be speed , power etc.
No, power isn't everything. Ring skills, meaning generalship, clever defensive technique, toughness and strength are equally important.
Power is great & all but I'd take speed any day of the week. Otherwise you could end up with fighters like Peter or Tua.
