Well then the question becomes why is the team not putting in effort, or not being able to compete at full intensity almost every game, resulting in dropped balls and missed tackles. Probably because they don't have ultimate faith in the game plan or the coach. It certainly didn't look like it last year.
They can show up to every game wanting to try their butts off, but if they don't truly believe in what they're doing, don't truly believe that if they just follow the game plan, they can win a comp, and they don't hang off AOB's every word as their leader, then it's going to result in negative things on the field and it's just going to get worse until he either gets removed, or there's a massive cultural shift headed up by a very strong leader within the group.
Guys like Bellamy, Wayne, Robinson have that aura that players will blindly follow. AOB doesn't have the reps on the board for that, and doesn't seem to have the personality to generate it either.
