Nope. They do not concentrate on the rotation as it is. You will find nearly all the players know exactly when they are coming on and going off during the rotation. Its only when there are injuries or other factors that this is changed (eg matchups).
Plus I reckon we have enough coaches to be able to monitor it all, we do it already.
well i actually saw a piece on channel 10 last year when willo was injured - he spent time in the box & he was saying how it was an insight working with the assistants & "spotting out those who are tired" to have them rested.... *shrugs* of course the players kno approx when they're coming off, they do it week in week out, its a set routine... but if we're rotating players from midfield via the fwd line for eg, you wont know how it will affect that certain player when they USED to be taken off at the 20min mark of 1st qtr but instead they are to spend the rest of the qtr as a small fwd... having to monitor one player is ok, but doing it for the whole midfield setup may be quite time consuming during the game.... but then again im not a coach.... =)
