honestly, that was the luckiest s**t ever...I was saying it before Rogan...FRONT KICK?! really?!?!? GTFO! thats a 1 in a BILLION KO....Look at Silva after the kick..he doesn't even wanna follow up cus he thinks Vitor isn't hurt that badly...then after Vitor lays there for like 4 seconds he sees his eyes and goes for the k!ll...even he thought it was a joke... REMATCH!!(I respect all f!ghters and am not a hater of Silva so blah blah shut up)
P.S. Jon Jones VS Shogun THAT IS NUUUUUUUTS
I dunno if you can call it lucky if he hit him where he intended. Just like a K.O. punch you throw it trying to land; sometimes it does, sometimes it K.O.s and sometimes it misses. You don't call every K.O. punch lucky so I don't think its fair to call this kick lucky just cause it hasn't happened in the past.
And I'm pretty sure he knew he was hurt... he felt the impact on the ball of his foot afterall. I think he didn't lunge in because of the way vitor fell. He rolled to his back and looked somewhat ready to defend (maybe an upkick or something). I think f!ghters are alot more cautious of getting caught being over anxious to finish someone that is hurt (e.g. smith v. drago)
