As usual, the topic has gone over your head.
TS is correct, we as fans put far too much stock in KO finishes. KO finishes don't always tell who the better fighter is, only who landed at that particular moment. Better fighters lose by KO all the time, 4 oz gloves + 15-25 minutes = even the best fighters on the planet can get hit once, and once is all it takes.
Did anyone think GSP wasn't worthy to rematch Serra so quickly after his KO loss?
Does anybody think Hendricks would KO Kampmann quickly in a rematch?
Fighters that possess the power to finish somebody on the feet have an advantage (JDS is the champ, he'll clearly be the fav), but this is the big leagues we are talking about here, everybody has power and anybody can finish the fight. Quick fights don't tell the whole story. There was alot we didn't get to see in the first JDS/Cain fight (grappling, takedowns, clinching, cardio, etc) why is everyone so convinced a rematch will play out exactly the same way?
