If Barrera did something like that to a nice guy then yeah, how bad. But let's remember it was Naz who has treated other boxers like S*** and humiliated them pretty bad. Well, he got a taste of his own medicine. Also, I forgot what round, the ref was separating them and Naz punched Barrera but Barrera quickly answered and a bit harder too! Like telling Naz "I ain't taking your shit!"
