BBM VII is a Week 17 contest wearing a 17-week costume. Survive your 12-person pod, then build every roster so it can explode in the final three weeks: correlated stacks, a real plan at quarterback, and exposure to the late-season games most likely to shoot out. Spread your entries across different builds instead of drafting the same team 20 times.
What Best Ball Mania VII Is
Best Ball Mania is Underdog Fantasy's flagship best ball tournament. According to InGame's April 28 rundown of the summer best ball market, BBM VII has a $25 entry fee, room for 672,336 entries, and a $15 million prize pool. First place pays $2 million, second pays $1 million, and there's a $100,000 prize for the best regular-season score.
The format is simple. You draft 18 players in a 12-team pod. There are no waivers, trades or lineup decisions. Each week, your highest-scoring players at each position are counted automatically. You draft once and the scoring does the rest.
That simplicity is the appeal. It's also why so many players lose: they draft the way they'd draft a season-long home league. BBM VII doesn't reward that. It rewards a roster that's good enough to survive the first 14 weeks and built to spike in the final three.
How the Tournament Pays: Pods, Then Playoffs
BBM VII runs in two phases. Weeks 1 through 14 are the regular season, played inside your 12-team draft pod. The top two teams in each pod advance. Everyone else is done.
The playoffs run in Weeks 15, 16 and 17, and each round is a fresh head-to-head pool. Establish The Run's Mike Herzig laid out the path in April: to win, you need to finish 2nd or better in your 12-team pod, 1st of 14 in Week 15, 1st of 12 in Week 16, and then beat a 667-team final group in Week 17.
Read that again. Your regular-season score doesn't carry into the playoffs. A team that scraped through in second place in its pod has the same shot in Week 15 as the team that led the whole tournament.
That one number should drive every draft decision you make. Advancing out of your pod matters, but it's only the cover charge. The roster you draft in July has to be built to beat 666 other finalists in a single week at the very end of the season.
How BBM VII Compares to DraftKings' Best Ball Millionaire
Underdog isn't the only big best ball contest this summer. DraftKings is running its own Best Ball Millionaire at the same $25 price, and InGame's numbers show it's even bigger on paper.
| Feature | Underdog BBM VII | DraftKings Best Ball Millionaire |
|---|---|---|
| Entry Fee | $25 | $25 |
| Prize Pool | $15 million | $20 million |
| First Place | $2 million | $3 million |
| Max Entries | 672,336 (smaller field) | 940,386 |
| Roster Size | 18 players | 20 players |
The DraftKings contest pays more at the top, but you're competing against a field roughly 40% larger. BBM VII has a smaller field and a playoff structure that best ball players have been studying for six years. Which one fits you depends on what you want. If you want the biggest possible score, DraftKings has it. If you want the deepest pool of strategy work and a tighter field, Underdog has it.
Plenty of serious players will do both. If you go that route, keep the roster-size difference in mind. Two extra roster spots change how deep you need to go at running back and receiver, so don't copy your Underdog builds straight onto DraftKings.
Strategy #1: Draft for Weeks 15–17, Not for Week 1
If most of the money is paid in Week 17, the schedule in Weeks 15 through 17 matters more than almost anything else on the calendar. That doesn't mean you draft a bad player because he has a nice December matchup. It means that when two players are close in price, you take the one whose team is set up to play a shootout late in the year.
DraftSharks did the early legwork in June, looking ahead to the Week 17 slate. The game that stands out is Ravens at Bengals, which had the week's highest projected total in that analysis at 51.5 points. The history backs it up. DraftSharks noted that the last five meetings between these teams with healthy starting quarterbacks produced combined totals of 51, 79, 69, 46 and 24 points. That's three outright shootouts in five games.
Two more Week 17 games also projected in the high 40s in that analysis: Giants at Cowboys and Lions at Bears, both at 49.5.
Those are early look-ahead numbers, and they'll move before December. But the logic holds. These games feature offenses that can score and defenses that can be scored on, and they match up players you're already drafting.
Week 17 Stack Targets Worth Considering
- Ravens–Bengals: Lamar Jackson, Derrick Henry, Zay Flowers and Mark Andrews on one side. Joe Burrow, Ja'Marr Chase, Tee Higgins and Chase Brown on the other.
- Giants–Cowboys: CeeDee Lamb and George Pickens for Dallas. Jaxson Dart and Malik Nabers for New York.
- Lions–Bears: Chicago's young core of Rome Odunze, Luther Burden and Colston Loveland, plus D'Andre Swift, in a divisional game with a high projected total.
The goal isn't to force all of these onto one roster. It's to make sure that across your full set of entries, you have meaningful exposure to the games most likely to decide Week 17.
Strategy #2: Stack, Then Bring It Back
Stacking matters in best ball for the same reason it matters in DFS. When a quarterback throws three touchdowns, someone catches them. If you roster both ends of that connection, you get paid twice for the same play. That's how a team gets the ceiling it needs to win a 667-team final.
The simplest version is a quarterback plus one or two of his pass catchers. The stronger version adds a "bring-back," meaning a player from the opposing team in a game you expect to be high-scoring. If Ravens–Bengals turns into the shootout its history suggests, a roster with Burrow, Chase and Flowers wins from both sides of the field.
If you're new to the idea, our NFL DFS stacking guide covers the mechanics. The principles carry straight over to best ball. The difference is that in best ball, you're committing to the stack for 17 weeks, so you want the quarterback and receivers to be tied together for the entire season, not just one game.
Strategy #3: Take Quarterback More Seriously Than You Think
The most common BBM mistake is the two-quarterback build that looks efficient in July and falls apart in December. 4for4's BBM VII guide found that three-QB builds have beaten two-QB builds in four of the six BBM years, and that four of the five best-performing builds last year included three quarterbacks.
The reason is simple. Quarterbacks get hurt, get benched and have bye weeks. If you only have two and one goes down, you're starting whoever is left every week, including in the playoffs. A third quarterback is insurance, and in best ball, insurance pays because the best score counts automatically.
There's a second QB angle worth noting. The same 4for4 guide pointed out that the top-scoring quarterback in 2025 posted the lowest QB1 total of the last five seasons, at 24.9 fantasy points per game. The elite tier didn't separate the way it usually does. You don't have to spend an early pick on a quarterback to compete. If you wait, though, roster three.
Strategy #4: Account for the Offseason Moves
Several high-profile receivers changed teams this offseason, and the market is still adjusting. When a player switches offenses, his average draft position often lags behind what his new role should be, in one direction or the other.
- A.J. Brown to New England. The Eagles traded Brown to the Patriots on June 1 for a 2028 first-round pick and a 2027 fifth. He's now catching passes from Drake Maye, who gets a proven No. 1 receiver.
- Jaylen Waddle to Denver. Miami sent Waddle to the Broncos in March for the 30th pick plus third- and fourth-round selections. Denver's receiver room is suddenly crowded, which matters for everyone else in that offense.
- DJ Moore to Buffalo. The Bills officially acquired Moore from the Bears on March 11. He's now catching passes from Josh Allen in an offense led by head coach Joe Brady.
Each of these creates a new stacking pair, and each changes the value of the teammates left behind. Moore with Allen is a natural best ball stack. Brown with Maye gives you a way into the Patriots that didn't exist a year ago. Waddle in Denver raises a fair question about how many targets go around in that offense.
None of these moves has been tested in a real game yet. That uncertainty is exactly why they're useful in a big tournament. If you're right before the market catches up, you're getting a high-ceiling player at a discount.
Strategy #5: Draft Now, but Know What Camp Can Change
There's a real case for drafting early. Rookies start reporting on July 17, with Seattle first up. Veterans follow between July 22 (Arizona, Carolina and Denver) and July 28 for most of the league. Until then, news is slow, and average draft position is relatively stable.
The trade-off is risk. Every summer, camp injuries and depth-chart surprises reshape the board. Drafting early means taking positions before the crowd does, and accepting that some of them will be wrong.
The smart approach is to pace yourself. Put some entries in now while you can draft against the field's early opinions. Hold back a meaningful share for after camp opens, when you'll know more about roles, injuries and holdouts. Don't burn your full bankroll in the first week of July.
Strategy #6: Diversify Across Your Entries
If you're entering more than a handful of teams, the biggest danger isn't any one bad pick. It's drafting the same team over and over. Twenty versions of the same roster means twenty versions of the same outcome. If your core gets hurt or flops, your whole portfolio goes down at once.
Instead, vary your builds on purpose:
- Different early-round structures. Some teams lead with running backs, some with receivers, some with an elite tight end or quarterback.
- Different stacks. Spread your quarterback-receiver pairs across several teams and several Week 17 games.
- Different late-round bets. Late picks are where tournaments are won. Don't keep taking the same upside handcuff or rookie flyer every time.
Every entry should be built to win, but they shouldn't all need the same thing to go right.
How Much Should You Put Into BBM VII?
A $25 entry looks small. Twenty entries is $500, tied up all season. Most entries won't advance. That's how a top-heavy tournament works.
Set a best ball budget before you draft and don't chase it. Our 1% bankroll rule guide was written with daily fantasy in mind, but the core principle applies. Large-field tournaments have high variance, so size your total exposure to what you can comfortably lose. If you're still deciding between best ball and a traditional league, our best ball vs. season-long breakdown covers the trade-offs.
Before you deposit anywhere, confirm that paid contests are offered where you live. Underdog and DraftKings both operate only in eligible states, so check your state before you sign up.
The Bottom Line
Best Ball Mania VII is Underdog's flagship summer tournament, and it rewards drafters who understand its shape. The pod is a qualifier. Week 17 is where most of the money is. Build every roster to survive the regular season and then spike at the very end.
In practice, that means stacking your quarterbacks with their receivers, aiming those stacks at late-season games with shootout potential like Ravens–Bengals, drafting a third quarterback when you wait at the position, and spreading your entries across different builds. Account for the receivers who changed teams this spring, and save part of your budget for after camps open later this month.
If you want a second shot at a seven-figure prize, DraftKings' Best Ball Millionaire runs at the same $25 price with a bigger field and a $3 million top prize. Either way, draft with a plan and a budget. A $15 million prize pool means nothing if you burn your bankroll before the season starts.
