Defy physics?
Photo 1: There are 10 yards between Moore and the defender. It’s probably further than that when he first spots Moore running
Photo 2: There is 5 yards distance when Moore starts his slide. It’s at this point the defender then DECIDES to lower his shoulder.
It’s not physics. It’s a conscious decision to break the rules.
I think people expect that athletes can defy physics and make some Matrix type maneuver to avoid contact, and I'm not sure if that is because most folks just don't understand physics or they see the action slowed down via replay.
