Hendricks used to be a beast, KOing guys spectacularly on his way to the top. He looks like his power has gone away and just seems to want to wrestle now. Not sure what has happened to him.
USADA drug testing happened to him. He hasn't been himself ever since it came into force.
Makes sense why he didn't want the testing that GSP offered to pay for in their fight.
Not to take anything from Wonderboy, he looked amazing out there and made it look easy.
