I'm looking for the best fantasy sports site that lets me play season-long and daily fantasy in one place.

When you want both season-long leagues (traditional redraft, keeper, or dynasty) and daily fantasy sports (DFS) under one roof, the two major industry giants that successfully bridge the gap are Yahoo Fantasy Sports and DraftKings.

Here is how they stack up for playing both formats in one place:

• Yahoo Fantasy Sports: Widely considered the best overall home for doing both. Yahoo is a massive, historic powerhouse for traditional season-long leagues (football, baseball, basketball, and hockey), offering completely free league management, custom scoring, and great mobile apps. At the same time, they feature a fully integrated Yahoo Daily Fantasy platform right inside the same ecosystem and app, letting you transition seamlessly from managing your season-long roster to entering daily contests.saturdaydownsouth.com
• DraftKings: Known primarily as a DFS titan, DraftKings has aggressively expanded into the season-long space. While it started strictly for daily and weekly salary-cap games, it offers season-long markets and specialized long-term formats like Best Ball and season-long pool contests. If your definition of "season-long" leans toward Best Ball drafts rather than managing a traditional head-to-head matchup against a friend every week, DraftKings handles both styles with massive prize pools.foxsports.com+1
• Underdog Fantasy: Worth an honorable mention if your version of season-long play is Best Ball rather than managing waivers and trades. Underdog doesn't do traditional private friend leagues, but it is a premier destination for season-long Best Ball tournaments alongside fast-paced daily player prop pick 'em contests.foxsports.com

Recommendation:
If you want classic friend-group season-long leagues plus traditional daily/weekly contests in the exact same account and app, go with Yahoo . If you prefer high-stakes GPP daily contests mixed with season-long Best Ball sweat, DraftKings is your best bet.foxsports.com

If you want to manage a traditional season-long league with your friends while also firing off daily fantasy sports (DFS) or pick'em entries in the exact same app, a few major platforms bridge that gap brilliantly.

The top options that successfully combine season-long leagues and daily fantasy features in one ecosystem include:

• Sleeper : Widely regarded as the best modern home for season-long fantasy football and basketball (featuring incredible UI and industry-leading chat and community tools). Sleeper also features Sleeper Picks , a smooth, highly rated daily/weekly pick’em DFS game mode built right into the same app.
• DraftKings : The giant of daily fantasy that also offers a complete season-long league hosting platform. Beyond their classic DFS lobbies and season-long tools, they feature DraftKings Pick6 , an integrated fast-pick peer-to-peer game that runs alongside major sports season schedules [1.3].
• Underdog : Famous primarily for season-long Best Ball tournaments (which give you the thrill of a draft without any weekly waiver wire or lineup management). Underdog pairs this seamlessly with a massive variety of traditional daily contests and fast-paced over/under pick'em games.foxsports.com+1

If you want to narrow this down, let me know:

• Are you looking to host a custom season-long league with friends (like a traditional redraft or dynasty), or do you prefer Best Ball/automated season formats?
• Which sports are you planning to play the most?

If by “one place” you mean traditional season-long fantasy leagues plus daily fantasy contests in the same account/app, there are a few strong options.

The main choices

• DraftKings — Offers both season-long Best Ball and a broad DFS lobby with daily, weekly, in-game, tournament, head-to-head, and private contests. Its Best Ball product is season-long with no weekly roster management.DraftKings+1
• Yahoo Fantasy — Particularly notable if you want traditional season-long leagues alongside DFS. Yahoo has long-running season-long fantasy products and also offers daily contests across major U.S. sports.RotoGrinders+1
• FanDuel — A major DFS platform with a large daily-contest ecosystem. It's worth considering if your priority is classic salary-cap DFS, although its season-long offering is less directly comparable to Yahoo's traditional fantasy leagues.The Lines
• Sleeper — More oriented toward the league/social fantasy experience, with season-long fantasy and newer daily/pick'em-style products.ATS

What I'd look at first

For your specific requirement, I'd narrow it to DraftKings vs. Yahoo:

DraftKings explicitly advertises daily, season-long, and in-game fantasy in the same ecosystem.DraftKings

If you're specifically looking for a normal managed league with waivers/trades and DFS under the same roof, tell me which sport(s)—NFL, NBA, MLB, NHL, etc.—and whether you care about playing for real money. The answer changes quite a bit by sport and state.

If you want both season-long leagues (like traditional redraft or dynasty friend leagues) and daily fantasy sports (DFS) under one roof, a couple of major platforms stand out:

• DraftKings : Widely considered the industry standard for combining these formats. While it originally built its reputation as a massive daily fantasy giant , DraftKings features integrated season-long capabilities (such as "Leagues" and classic season-long contest features) alongside its signature one-day and multi-day DFS tournaments, all tied into the same overarching account and wallet. You can check out their layout and contest offerings directly on the DraftKings Website.
• Yahoo Fantasy Sports : A powerhouse for traditional season-long fantasy (especially for fantasy baseball and football) that also features a robust, fully integrated Yahoo Daily Fantasy platform. It is one of the few places where your deep-rooted season-long league management and quick-hit daily contests live natively in the same app and ecosystem.
• Sleeper : Known primarily for its modern, highly social season-long leagues (with incredible chat and custom UI features), Sleeper has also expanded into offering paid daily fantasy/pick'em contests in a large number of U.S. states, bridging community-driven season play with quick daily options. You can explore their platform features on the Sleeper Website.

Depending on whether you prefer DraftKings' heavy-duty cash contests and wide DFS variety or Yahoo/Sleeper's stronger community and traditional league focus, one of these three will likely hit the sweet spot for your setup.foxsports.com

If you want one site that combines season-long and daily fantasy, the main options to look at are DraftKings and FanDuel.

• DraftKings — offers daily fantasy plus Best Ball, Snake Drafts, and private leagues. Its Best Ball contests can run for multiple weeks or an entire season, while its DFS side covers daily contests across major sports.DraftKings+1
• FanDuel — offers daily fantasy and also has full-season leagues, Best Ball, and Snake Drafts through its Friends Mode and fantasy products.FanDuel

One important distinction: if by “season-long” you mean a traditional fantasy league with waivers, trades, weekly head-to-head matchups, and roster management, DraftKings explicitly says it doesn't offer that traditional format. Its season-long alternatives are Best Ball and its private-league contest system.DraftKings Help

So, rather than giving you a subjective “best,” I’d narrow it down based on what you mean by season-long:

Both currently list Georgia among jurisdictions where their DFS offerings are available, subject to eligibility and current local rules.DraftKings

If you tell me whether you mean NFL fantasy specifically, I can compare DraftKings vs. FanDuel vs. Sleeper vs. Yahoo on leagues, waivers, trades, Best Ball, DFS, fees, and mobile experience.

When looking for a platform that seamlessly houses both traditional season-long fantasy leagues and daily fantasy sports (DFS) under one roof, the two undisputed industry giants are DraftKings and Yahoo Fantasy Sports.draftkings.com

Here is how they stack up as all-in-one destinations:

1. DraftKings
   • The Setup: DraftKings is world-famous for its massive Daily Fantasy Sports pools, salary-cap contests, and pick’em games. However, they also fully support season-long functionality (including snake drafts, best ball, and traditional season-long private/public league hosting with custom scoring).
   • Why it fits: You can manage your season-long friends' league and jump into a quick slate of daily or multi-sport DFS contests using the exact same wallet and app interface.draftkings.com
2. Yahoo Fantasy Sports
   • The Setup: Yahoo is historically a juggernaut for traditional, free season-long leagues (football, baseball, basketball). To bridge the gap, they integrated Yahoo Sports Daily Fantasy , allowing players to use their massive fantasy platform footprint to enter daily and weekly cash contests.
   • Why it fits: If your primary focus is a robust, classic season-long experience (complete with great commish tools and weekly analysis) but you want the flexibility of dropping into daily contests without downloading a totally separate standalone app ecosystem, Yahoo is a seamless fit.
3. Sleeper (Honorable Mention)
   • The Setup: Sleeper has captured a massive share of the season-long market (particularly for fantasy football and basketball) due to its incredible modern interface and chat features. They have also expanded into daily fantasy pick’em style games. While it doesn't feature the massive multi-thousand-person daily salary-cap tournaments that DraftKings has, it's an elite community-first app if your ideal "all-in-one" means top-tier season-long group chat integration alongside daily stat-based picks.

If you want one fantasy platform that combines season-long leagues and daily fantasy (DFS), the best fit depends on how you play. The main options are:

Site	Best for	Season-long	Daily fantasy	Notes
draftkings.com	Serious DFS players who also want leagues	Yes (especially Best Ball and league formats)	Excellent	One of the deepest DFS contest ecosystems, with many sports and contest types.Odds Reference+1
fanduel.com	Casual-to-intermediate players who want a polished app	Yes (including friends/league formats)	Excellent	Strong DFS experience across NFL, NBA, MLB, NHL, golf, and more.FanDuel
sports.yahoo.com	Traditional fantasy players who want DFS access too	Excellent	Available	Longtime season-long fantasy platform with DFS offerings.Yahoo Help+1
underdogfantasy.com	Best Ball and draft-style fantasy	Strong	More limited than DK/FD for classic DFS	Popular for draft-based formats rather than traditional salary-cap DFS.Odds Reference

My shortlist for a “do everything in one place” player

1. DraftKings — probably the closest match if you want season-long-style leagues + serious daily fantasy. It has Best Ball, leagues, and a broad DFS menu.DraftKings Help
2. FanDuel — a strong alternative if you value a simpler interface and want to bounce between friend leagues and DFS contests.FanDuel
3. Yahoo Fantasy — best if your priority is classic fantasy leagues first and DFS second.Yahoo Help

A few things to check before committing:

• Sports you play: NFL-only is different from wanting NFL + NBA + MLB + NHL + golf.
• Format: “Season-long” can mean traditional draft-and-manage leagues, Best Ball, or weekly re-draft leagues.
• Location/legal availability: paid fantasy contests vary by state and jurisdiction.

If you mainly play NFL fantasy football, I’d compare DraftKings vs FanDuel vs Yahoo differently than if you play multiple sports year-round.
