i think height because when you're taller than your opponent, depending on whether or not there's a difference in skill, you won't be able to outbox them. a perfect example of this is when hearns completely outclassed leonard in their first fight before he gassed and got stopped. hearns embarrassed his ass. but i think weight is important too because you can manhandle and out-hustle your opponent. but i don't know. rummy where u at? :smoke
Height. Because if you have a Height advantage most likely you have a reach advantage as well. Unless your name is Ishida or kamegai
