if we're talking about fluke knockouts, the Silva front kick looked mighty flukey..I mean that move isn't even design to knock people out. I'm not saying Silva wouldn't have won otherwise but we would never know why don't we lobby for a rematch
I don't consider that a "fluke" KO at all coming from someone with the well-documented history of unusual strike finishes as Silva.
What is a fluke? A fluke is the Vitor punch thrown at Randy Couture that cut Randy's eyelid! THAT is a fluke. Nothing anyone trains for.
Front kick to the face is a legitmate striking technique and clearly, when applied with precision and timing (an area that Anderson excels at), can have devastating results. It's that most other fighters don't have that amount of accuracy and usually throw either as a defensive maneuver or throw it on a prayer hoping it might hit something. Condit has thrown a few that way during past fighters (GSP).
If I remember correctly, Silva set it up with with a couple low kicks then went to the face, leaving Vitor reaching to block a low kick, with face totally unprotected.
Also, the level of committment Silva made to that kick, if you watch in slo-mo, shows he was clearly putting everything behind it, not just throwing out a jab.
Vitor, like most other strikers, with Silva, has at best, a puncher's chance.
