Your futures book moves every week.
A future is not a lottery ticket that disappears into a drawer until January. Sharp Sheet marks the league's positions as the real market changes.

The whole league watches the same board
NFL leagues use one verified championship market. When the sportsbook price changes, Sharp Sheet records the move and uses it to mark every held position tied to that team.
If your team gets hot and the market starts believing, the position adds value to your bankroll. If the season turns bad, the drag shows up before the team is mathematically dead.
Price movement creates decisions
A position that doubled in value might be worth selling. A contender that had one ugly Sunday might be available at a discount. A manager short on bankroll might have to list something they would rather keep.
That is where the game stops feeling like set-it-and-forget-it fantasy. Your draft gives you a starting book. It does not make the decisions for the next four months.
The tape stays clean
Sharp Sheet keeps the first captured price, the current mark, and the source behind the board. New drafts and weekly picks pause if the provider data is stale instead of filling the screen with fake lines.
At season close, positions settle into a final closed or void record. Nothing stays tradable after the football result is official.
