Draft a roster, never set a lineup again. Here's how the format actually works, where it differs from DFS, and the roster-construction ideas that decide most tournaments.
Best ball is a draft-only fantasy format. You draft a roster, and that's the last decision you make. Each week, the scoring system looks at everyone you drafted and automatically counts your highest-scoring eligible players at each position. No start/sit calls, no waiver wire, no trades, no Sunday-morning panic about a questionable tag.
Because your best lineup is chosen for you after the games, you're never punished for benching the guy who went off. You're only ever punished for not drafting him.
People lump these together because both are "fantasy you can enter for cash," but they're structurally different games:
That last row is the important one. In DFS, everyone can roster the same player, so the question is how many people will — which is why ownership is the whole game. In best ball, a player you draft is off the board for everyone else in your draft, so the question is which shape of roster survives a season.
Say your league starts 1 QB, 2 RB, 3 WR, 1 TE and 1 FLEX. After the week's games, the system sorts your drafted players by what they scored and fills those slots with the best eligible results. If your third-best receiver outscored both of your running backs, he takes the FLEX. You did nothing; it just happened.
Two consequences follow, and they drive every good best ball decision:
A player who scores 4, 4, 4 rarely cracks your lineup at all. A player who scores 2, 2, 24 gets counted the week it matters. Consistency is worth much less here than in a format where you must start someone.
Because bad weeks are discarded automatically, extra bodies at volatile positions genuinely help. Your 6th receiver isn't dead weight — he's another lottery ticket that only costs you when he takes a roster spot.
Exact numbers depend on your site's roster size and scoring, but these are the common shapes in a standard 18–20 round build:
One is fragile: a bye or an injury leaves a hole in a slot you must fill. Three is fine if you waited. The bigger question is which ones — a quarterback attached to receivers you already own is worth more than his raw projection suggests.
The position with the most injury turnover, which cuts both ways: your starters get hurt, and so does everyone else's, making backups suddenly valuable. Handcuffs and ambiguous backfields are worth more here than in formats where you have to guess right in advance.
Usually the largest block. Receivers are volatile week to week, and volatility is exactly what the format pays for. This is where extra depth earns its keep.
A thin position. Either take one of the few genuinely reliable options early, or take several late and let the format sort them out. The middle is where drafts go to die.
If your site uses a FLEX, remember that it quietly raises the value of whichever position has the most weekly spikes — usually receiver.
A stack is a quarterback plus his own pass catchers. When that quarterback throws four touchdowns, the receivers catching them score too — and best ball counts all of those results in the same week.
Here's the intuition. Two players who each average 12 points but spike in different weeks give you a steady, unremarkable total. Two players who spike together give you the same average with a much higher best week. In a format that counts your top scores and throws away the rest, the second roster is worth more even though the season totals match.
The same logic drives DFS lineup building, which is why our optimizer has a stack control: it forces a quarterback to be drafted alongside a set number of his own receivers. Different format, identical reasoning. You can read how we handle it in the tool tutorial.
Big best ball tournaments are top-heavy: a large share of the prize pool sits with a handful of finishers. That changes what a "good" roster is. A roster built to finish reliably in the middle is a roster built to lose slowly. You need outcomes that are not just good, but unusual.
This is the one idea that carries over cleanly from DFS tournaments: in a huge field, being right isn't enough — you have to be right in a way most entries aren't. If a roster shape is obvious enough that thousands of drafters land on it, winning with it means splitting.
Two honest cautions. First, "be contrarian" is not a strategy on its own; being different by drafting bad players is just losing with extra steps. Second, entry volume multiplies both your chances and your costs — decide what you're willing to spend before you start, not after a bad week.
Best ball is a draft-only format. You draft a roster, and every week your highest-scoring eligible players are counted automatically. There are no lineup decisions, no waivers, no trades, and no start/sit calls. Your optimal lineup is scored for you after the games finish.
DFS is a salary-cap game played one slate at a time: you pay for players out of a fixed budget and rebuild every week. Best ball is a season-long draft with no budget, where you pick in turn against the other drafters. DFS rewards weekly reaction to news; best ball rewards drafting a roster shape that survives a whole season without your input.
No. That is the entire point of the format. Once the draft ends you are done. Scoring picks your best eligible players automatically each week, which is why the format is popular with people who like drafting but not weekly management.
Stacking means drafting a quarterback together with his own pass catchers. When that offense has a big day, several of your players spike in the same week, and best ball counts all of them. Because only your best scores count, correlated weeks are worth more than the same total points spread evenly across unrelated players.
Most drafters take two or three in a standard 18-to-20 round build. One quarterback risks a bye or injury leaving a zero in a scoring slot; four rarely earns its roster spots. Two is the common baseline, with a third added if you took your first one late.
It can be, and it can also lose money. Large best ball tournaments are top-heavy, meaning most entries lose and a small number win big. Anyone promising guaranteed profit in any fantasy format is selling something. What you can control is roster construction, the cost of your entries, and how many you play.
Not directly. Slate Signal is built for weekly DFS: ownership projections, leverage scores, contest simulation, and a lineup optimizer for DraftKings-style salary-cap slates. The ideas transfer — correlation, ceiling, and being different from the field all matter in best ball tournaments too — but the tool itself optimizes salary-cap lineups, not snake drafts.
