I played a game of Oztag against him a few years back. It was the last year he was at Manly and I was lucky enough to have a chat to him afterwards. I remember thinking at the time that he looked way too small to be playing in the forwards at NRL level. He was similar height to me and I reckon he had about 10 kilo's on me at the time.
Looking at him the other night, I reckon he'd be a good 30 - 35 kilo's heavier than me now. He is a beast.
On a side note, he was a surprisingly nice guy. I thought he'd be a bit of a dick, being an NRL player and all but he struck me as a genuinely good guy.
