St Kilda have conceded their attack was too focused on Max King during a failed AFL finals bid last year as they attempt to build a new game plan under Ross Lyon.
Star forward King is vital to the Saints' success, but will miss at least the first month of Lyon's first season back at the helm after undergoing shoulder surgery in December.
The 22-year-old's absence comes with Lyon facing a tough ask to get the Saints off to a good start, with fixtures against three of last year's finalists in the opening five rounds.
