Shai will be an amazing player for us but he is so light he gets thrown around and bumped too easily atm for finals imo, Castagna is harder in the contested stuff for mine. I feel for Miles, has done everything he can and was one of the few that could hold his head up from last year (despite having it nearly torn off nearly every game). Broad is good, he rode that intensity well for one of the inexperienced blokes in the team and will be better for it.
I think you don't mess with the squad, they are blooded now, they got a taste and Geelong threw everything at them early, and they soaked it up.
