Question? What dictates when the fight is over...the ref or the tap? I remember an interview with Herb Dean after the Henderson Pettis fight where he stated that he did not hear the verbal submission but said that the correct process would have been to wait for him to stop the fight. Now, Pettis showed good sportsmanship (which I agree with). But, Palhares is getting a lot of flack for not releasing after tap and only when the ref intervened (actually not even then) but that raised this question for me.
