I'd agree that he doesnt kick us out of trouble, but nor is his kicking game bad. I'd say kicking out of troube is way easier said than done. There are very few halves in the comp that actually can, and those few that occassionally manage to typically do so after a strong run where a forward has taken multiple defenders out of the line or made a quick play the ball, thus less kick pressure. Again, i dont see our forwards ever having done that. Brooks kicking stats are actually comparable to most other halves. In fact he has slightly less kick errors per game than the bloke were chasing to take his spot. The out on the full and 7 tackle set chat is a complete myth.
Decision making is debatable. There isn't really any stat specifically to measure that. But, his/the Tigers attacking output compared to other teams and factoring our defence is respectable. He does make his fair share of errors, but again it is at a rate comparable to most halves.
