Anybody notice the 3rd round knockdown was identical to a move from the 1st fight?

Also, looking at the two side by side again, it's clear that JMM brings his feet under him better in the 4th fight, stepping forward, so that when he throws the right, he can pivot into the shot with his weight behind it. Lunging forward diminishes the blow.

I'm curious as to whether that's something Marquez has continuously improved on; knockdowns against Pacquiao and Barrera show his mistake, as well as the Floyd fight, but in the Fedchenko and last Pacquiao fight, he's looking more balanced and bringing his feet under him better when advancing instead of having them lag behind.
