In a purist boxing style yes, his footwork is akward. In a Muay Thai Style his footwork is also akward. It's good though that he has good speed for a heavyweight and good explosive power which helps him destroy his opponents and overcome them. He's also pretty darn accurate. But good observation.
I'd be hanged if I said this infront of the Aussie public who think he is flawless. I also think his weight transfer is terrible and he could use much less power if he shifted his weight properly but again, his sheer speed and explosive power makes up for it.
