Re my posting above, the figures probably show that despite Collingwood being in the top 2 "spenders" in the league over the last 15 years they've got one premiership (after a draw initially). As long as a club has a lower limit of spend they can and have got results. Hence they should cap the spend if they think it's an advantage (even if the facts don't indicate this). Rucci was very selective.
I've spoken to a friend who is a full time assistant coach for a state based team. He reckons he could easily do it part time, there's only so much players can take in, so many meetings, new ideas etc. often these coaches are just attempting to justify their positions.
