Closing season ADP is built in, so value, capital and projected points work the moment your entries are in. To use a different set, drop a rankings CSV in as well; it overrides the built-in table and joins on player ids.

Best Ball Domain reads the entry export from Underdog Fantasy and turns a few hundred rows of picks into the things you actually want to know about a best ball portfolio: which players you are on, how your rosters are built, whether your quarterbacks are stacked, whether you drafted ahead of or behind the market, and how every team is doing once the season starts. It works for Best Ball Mania, The Puppy and any other Underdog best ball contest, and it is free. It is an independent tool and is not affiliated with Underdog Fantasy.
Every player you drafted, with the number of entries holding him and your exposure as a share of the portfolio. Exposure is measured against whatever is currently in view, so filtering to one contest or one build shape gives you exposure inside that slice rather than across everything. Each player opens to show his average draft position against yours, which rounds you tend to take him in, who you most often draft alongside him, and every team of yours that holds him.
Builds are counted by position, so you can see how often you end up on three quarterbacks or eight receivers. Teams are also labelled with structural types (Zero RB, Elite TE, Anchor WR, Robust RB, Bully QB and others), and every rule behind those labels is editable, because everyone defines them slightly differently. Each team gets a grade built from its ADP value, draft capital, build, stacking and playoff correlation.
A team stack is a quarterback paired with a pass catcher from his own club. The tool finds them automatically, reports how many of your quarterbacks are stacked and how deep, and then counts correlated players separately for weeks 15, 16 and 17, since each playoff round is decided by a single week of football rather than a season.
Closing average draft position is built in, so value works the moment you drop a file in. ADP value is your pick number minus the market's, summed across the roster. Draft capital weights the same comparison by where in the draft it happened, which matters because a bargain in round two is worth considerably more than the same number of spots gained in round eighteen.
With a free account, live scoring shows points for every roster as the games are played, scored the way Underdog scores them: half-PPR, with the best QB, two RBs, three WRs, a TE and a flex counted each week. Each team also gets a season total, with final scores for weeks already played and projections for the rest.
Your export says what you drafted, not who you are playing. The Best Ball Domain pod loader, a free Chrome extension, fills that in: your Underdog pods load into the site, and every team shows where it stands in its pod, how far it is from the advancing line, who the other eleven drafters are and what they took, and its chance of finishing in the top two, updated as injuries and big weeks happen.
Each team gets a modelled chance of advancing and an expected value against the field, fitted on five Best Ball Mania tournaments. The FAQ explains every coefficient, what was thrown out and why.
