in regards to your video 2-0, I've seen that fight like 10 times and that knockdown probably 20 times, including 4 times yesterday. Him being on the ropes before the knockdown doesn't cause it. They fight for a good 10 seconds before the knockdown happens after pac is off the ropes, then pac catches him with an awkwardly thrown uppercut right on the button. His foot is on the A on the Tecate ad on the ring. Like I said, both knockdowns happen towards the middle of the ring and the rope a dope move didn't cause the knockdown
