I think that fighters that absolutely whoop his opponents as* for 3 or 5 rounds, is more impressive, cause you can't say that his opponent didn't had the chance to do this or that during the fight.
But, fast victories can't be forget too.
Some can, but some not.
Houston Alexander x Keith Jardine
- OH MY GOD ! WHAT A MONSTER!.... or not, Houston proved to be a joke..
He impressed a lot of people, but we all know, Jardine don't have the best chin, and Houston isn't that great.
Another mentions: Paulo Thiago x Kos, Irvin x Houston
Silva x Griffin
- A fast victory, but.. what a way to impress. Silva took less than a round, to show how good, and how dominant he is. I really don't believe how I picked Silva UD in this fight, one of my worst call ever
Another mentions: Marquardt x Kampmann
IMO, is more impressive whoop for 5 rounds, or, whoop for less than a round, the way Silva did. Besides that, isn't all that impressive..
