The best-possible SuperCoach team for Round 17 scored 1,901: 17 players count, with Phillip Sami doubled as captain and the lowest score dropped. That is 488 points clear of the best score any coach actually posted this round (1,413).
This is the best team you could have fielded in Round 17 with hindsight, scored the way SuperCoach scores a real team: 18 players are picked — the starters and the reserves — your single lowest score is dropped, and your highest scorer, the captain, is counted twice.
The struck line is the score that dropped; the circled C is the captain on double points. The reserve count and the shape come straight from the competition's own rules, not a fixed number, so this stays correct if the game changes. There is no salary cap: it is the pure ceiling for the round.
