As hard as it is to say. I did notice Ball got totally skinned when chasing a loose ball up front in a promising position not long after he came on. Workhorse yes but Pacey no. With the long haul to Perth and midnight kickoff perhaps suited better to younger legs.
Bally played to high, you need play him a bit deeper and hassle players, Van Hattum would have been better impact. I guess we got out coached.
