Looking at game day tactical coaching, there has been a change this year.
In 2016 Wooshas right hand man on game day was Neeld, Head of Player development. This year its Rob Harding, Opposition strategy coach.
This is probably a better choice when you are actually trying to win games rather than trying to train young players.
In spite of this change Woosha still adheres to maintaining shape and structure and at best uses "accountability" rather than "run with"/tagging. This is in spite of several teams tagging key players and seemingly winning games on the back of it, ( eg. Sloan) while we seem to have tried and abandoned even the accountability strategy, which worked with Trav on Gaff and BJ on several players up to Round 8.
Even when the opposition disturbs its own structure by tagging Zac Merret, we dont respond by tagging the oppositions ball magnet/ damaging player.
I cannot say for sure we would benefit by tagging, but it looks like Woosha is idealogially opposed to it and has not selected a player to specialise in it, thus its not a tool he has available even when an opposition player is really really hurting us at crucial times in games.
