It looks like Jackson could have finished Punk at any time but chose to toy with him instead pissing off Dana White who said he'd probably never fight inside of the Octagon again because of that. Jackson could have toyed with CM for 2-1/2 rounds and finished him in the 3rd but he didn't appear to even try to finish him. I saw him on top of Punk in mount and it looked like he was looking at his corner for instructions. I was like, "Is this a work? Is he throwing the fight?" Either way, why don't you think Jackson didn't finish Punk?
