Wasted time and wasted money. Another step away from footy, and footy players. Give them a break from training, let them do what they want to do, and then crank up the pre season, working on fitness and skills. All this crap about game plans and strategy is a con to keep assistant coaches and other hangers on in money.
All those game plans and tactics last as long as the first miskick or dropped mark. It is then that the natural footy players like Walters, Hogan, Hamling and Darcy should take over. Not the "stoppage specialists", runners and umpires
