Nathan Sharpe (72)
He's not running a race. That's a running stride for anyone going into contact. Like all great ball carriers and tackle busters.
I tried my best to get a shot from that youtube clip of the highest knee position in every stride coming into that contact.
Judge for yourself as to whether that last frame shows "normal" running knee height, based on what he did to that point. I admit he's picking up pace in the first couple of steps, but you'd be hard to find a physiologist who calls that a standard running stride, based on the placement of his plant foot. He's not sprinting with his knees up at this point, he's just a couple of metres after getting knocked down by another defender.
