David Benavidez, Danny Garcia and Robert Guerrero all have dislikeable dads but IMO they all take a back seat to the scumbag that is Teofimo's dad.
1. Bill Haney 2. Nonito Donaire Jr. (Sr. wanted Gaballo to KO Nonito and was willing to train Gaballo in a rematch to do so) I like Angel Garcia. I think he's a real one and he's corny-funny.
Probably Teo's dad is most annoying. But in terms of utter scumbagness it has to be the eye gouger coward John Fury.
