when should two fighters have 4 fights between them?

[-AZZA-]

its rare and most of the time seems pointless, but if 2 fighters have theyre first fight, one of them wins, then they fight again and its a draw, then they fight again and the other fighter wins, should they fight again ?

yes if it's a great trilogie, but i am very happy that ruiz didn't face holyfield a 4th time

if 2 of them are controversila, then yes.....also if they were great trilogies and if the fighters are still in their prime...
