Predictive theories of boxing matches

[SugarBoxing]

I know 2

1. Triangle Theory

condition

fighter A won over fighter B

fighter B won over fighter C

statement

fighter A will win over fighter C

evaluation

Does not really work, only in trivial cases when there is a HUGE level difference between fighters

counter example

Sugar Ray, Hagler, Hearns, Benitez, Duran and their cross fights

2. Max Powerism 101

condition

bigger [fighters] are better

newer [fighters] are bigger

statement

newer [fighters] are better

evaluation

cannot be really assessed because is usually applied to fighters from different generation

consider Broiler chicken and the one grown in a farm: which is more tastefull?
