Do you know what the Halo Effect is? Hendricks isn't getting dominated like everyone else GSP fought. He must be winning.
Break down how you scored the fight.
Simply put the 3rd and 5th there is no argument were GSP's. 2nd and 4th were for Hendricks. The 3 judges unanimously scored these 4 rounds. The first was the deciding round.
Round 1 was 19-18 in significant strikes for GSP. 27-26 in total strikes for Hendricks. Both had 1 TD each. GSP had one submission attempt Johny zero. Close round that coiuld go either way. Johny shouldn't get extra credit for doing better than all the others who lost before him. I believe if you watched that fight on a computer played out with Random avatars like a video game and scored it you would see it as a close fight that could go either way.
GSP outstruck Hendricks overall, 4 of the rounds were within 5 strikes or less but the one other round GSP outstruck Hendricks 31-15 in significant strikes. More than double but that was a 10-9 like all the other razor close rounds? In order to be the man you gotta Beat the Man and Johnny failed to do that.
