Firstly I accept Schuster had to go, but that to me was relating to commitment issues.
I think its important not to create issues that are contrary to the facts. There was a lot of perception that Schuster wasn't a good defender. In 2021 his tackle efficiency was around 88% as I can recall. And he was one of only three 80 minute forwards. This year though he played only 4 games his tackle efficiency was 94.7%, Granted these were Blacktown games and not the full 80 minutes, but it hardly suggests he has defensive problems. This year Brooks tackle efficiency is 83.5%, Croker's is 89.5% and only Jake is superior at 95.1%.
Now granted he's playing a lower grade but that doesn't get passed the fact his tackling was better than most. I know many say he misses tackles. OK. Most players do. In this last game Brooks missed 4, Talau 5, Lodge missed 3 and only made 7 tackles. I hear no comments about that. As I've indicated many times one's perception is inevitably biased and dependent upon what you are looking for. Schuster wasn't pushed because of defense, he was pushed because of lack of commitment to his training and a sense of attitudinal problems.
