He had excellent timing, and would accelerate on to the ball. There are some skills like that which are different from pure speed. Blokes like oudenryn who were really fast but had no footy skills didn’t do as well.
There was an easts player who was reportedly the fastest in the game (forget his name now) who rarely knew how to put himself in the right position to score.
I think in that 87 premiership year that the bug was injured for a while and came back through reserve grade. In his return reserve grade game he scored about 3 tries and was a class above. He always seemed pretty fast to me live.
