Roster checkup
Add your roster. The checkup grades each position group against every possible room in the 878-player pool, reads your roster's age, and flags your biggest need before you negotiate your next trade. Same computed values as the calculator, same 0–1,000 scale. Nothing leaves your browser, no account.
How it grades rooms. Each position's strength is the sum of your top starters' model values (1 QB, 2 RBs, 3 WRs, 1 TE in a 12-team league, rescaled for 10- and 14-team). That sum is ranked against every possible same-sized room in the player pool (the best N players, the next N, and so on). 90th percentile means your room is as strong as or stronger than 90% of possible rooms. Only players with nonzero value are counted. The startable universe.
How it reads your window. Roster age is value-weighted: your best players move it more. 25.5 and under reads rebuild; 27.5 and up reads win-now. The verdict routes you to the matching view of the calculator's timeline toggle: same values, re-weighted for your window.
Honest limits. 12-team superflex starter counts are the baseline; your league's lineup rules may differ. Percentiles describe the player pool, not your league-mates' rosters. And the checkup can't know who your league-mates will actually trade. That's what the offer builder is for.
