Snapshot
Private alphaWhat ships today
01
Player values from z-scores across all nine categories, with punt builds, timeframes, and percentages computed from makes and attempts rather than averaged.
02
Automatic preseason forecasts from prior seasons of game logs, with manual overrides and CSV import and export. Missing data stays missing; unknown is never counted as zero.
03
Pick tracking with undo, conflict-safe saves across devices and recovery from dropped connections, rehearsed end to end on a full 156-pick draft.
04
Draft advice ranks the remaining players by your punt strategy and your team's category balance.
05
Projected league standings and hypothetical trade analysis, with every team compared category by category.
06
Add and drop scenarios with category impact and dated injury notes. Real waiver eligibility stays with the league host and is never guessed.
