I recall Talia being pretty poor last season in his three games, but some talls just take longer than others. Odds are that the extra year of development under a coach who believed in him was the catalyst for his improvement, rather than being frozen out.
Happy to have McCartney at the Demons because he'a a great development coach, but he really shouldn't be a senior coach.
Think Talia was more a personality clash than development most dogs fans were stunned he was continually not selected given his VFL form
