...his KO punch on Liddell.
I wasn't even looking for it, but just noticed at the very end of UFC 71, as they're showing the night's highlights, they show a previously unshown angle on QJ's KO of Chuck.
Right before the KO punch, Chuck was defending by hiding his head against QJ's body, so Quentin came down with an illegal elbow right to the side of Chuck's face, that knocked him back to the mat setting up the KO punch.
You can't see it on the regular broadcast because the elbow happens fast and right as BJM cuts across screening out the blow from the viewers.
I'm not saying this was intentional, nor that Jackson doesn't deserve the win, just saying I haven't heard anyone else mention this before and I only caught it by chance.
