Is it boxers duty to entertain??

[ICB]

especially when the fighter who is showboating gets KO'ed.

And you find that boring didn't you ever see Judah vs Tszyu ??

You are talking about one fight in many.

Watching the same boxers, time and time again, enter a ring and after a round or two, starts "showboating" when they "think" they have the other fight hurt or in trouble, only to be KO'ed or lose the fight on points, does get boring. JMO

Jones vs Tarver 3 comes to mind, im big Jones fan but that was damn embarrassing night for Jones keep taunting Tarver like that and doing nothing at all.
