Just watching again... the one that really stood out for me was a pretty ordinary try, but Peachey was involved over on in the very right hand corner, the ball went back to the other side and he scored in the very left hand corner. He was an absolute freak, but tries like that are just about backing up and never stopping moving.
The other one... the one where he got the grubber past Minichello near the end. I've seen that so many times and still can't work out how he got there. Like he froze time and the video came back on a second later.
