doing it after you win>>>before the f!ght
serious entrances>>>>flamboyant entrances
Flamboyant entrances garner more fans for some. Mayhem Miller, Sakuraba(Legend), Genki Sudo(Legend), Mo Lawal, Anderson Silva used to do it. All of them are serious competitors...But they all know how to have some damn fun. Some guys actually like going in there and throwing down, win or lose. Not everyone f!ghts with the "I'm gonna k!ll this guy mentality"
I sure didn't and still had a winning experience most of the time. What you do before and after a f!ght doesn't matter. Only on lookers care about entrances anyway.
