This is pretty good advice if you insist on boxing at lower lvls, keep atk and def higher as said hitting more and not getting hit are more important in a boxing situationBest would be maxed at 113 cb, 99 99 99.
For lower levels in boxing:
80 att, 65 str, 80 def
Strength is the least needed of the 3. You need to hit often, and not get hit. High hits dosent matter because you don't max too often with your fist anyways.
