I think it would be between Booker and Ingles.
Australian dudes can bring it - I've seen it with my own eyes. It's in their genes or something. But Booker has the best combination of size, speed and power so I think he'd be the favorite.
Dark horse is Kanter, I liken him to Homer Simpson in the episode where he becomes a boxer. He may just tire everyone out by taking repeated shots to the head.
Hey I already used that in this thread for Ingles.
