In my opinion Hendricks' was NOT tapping his hand movement merely resembled the tap out motion, which is not uncommon in grappling/JJ, though I cannot recall many instances in the UFC of that happening.
Dana looked like a bored boyfriend as GSP kept talking about his personal issues. I also got the impression that Dana was trying to downplay GSP's weirdness after the fight by focusing on the decision drama instead of the bizarre shit his fighter was saying. Maybe GSP was concussed, combined with his self proclaimed emotional behaviour led to him acting derpy, but for obvious reasons Dana isn't even gonna mention the potential for brain injuries after a fight.
As for the scoring, that's the good ole 10 point MUST system at work once again completely failing MMA. Rogan talks about it roughly 1 minute into that video Fedor posted.
"A system of scoring whereby the winner of a round must receive ten points, and the loser of the round nine points (eights points, if knocked down; seven points, if knocked down more than once and thoroughly dominated by his opponent). If there is no clear winner, each boxer must be awarded ten points"
Applying that system to MMA doesn't work correctly because;
A.) there are no standing 8 counts so the exact meaning of a "knockdown" is treated differently sometimes
B.) say both fighters throw 10 shots each that all land, one guy does little damage the other gets smashed. technically both fighters may be awarded equal points because "there is no clear winner" , since 10 strikes = 10 strikes.
Judges have too much room for interpretation, leading to them having vastly different takes on the same fight even if they are honest. This system was not designed for MMA and needs to be tailored for the sport
