Looking at the comments, it’s fairly obvious that BA was going to be criticised whatever side was put out.
Been accused in the past of hammering his team into the finals and not taking that seriously enough. So he rests players who have hardly missed a game to freshen them up for the finals.
Then if the team gets beat heavily, bang , he’s an idiot for not picking his first choice. At least with no reserve grade comp, players who have not had many games and have trained continuously get experience , and the rest for the others should be of benefit.
