Summer League Stars: Which NBA Rookies Are Fantasy Gold in 2025

Composure and vision running the offense—he's already arrived
Cooper Flagg's performance at Summer League confirmed he's NBA-ready as both a scorer and facilitator.

Each July, the Las Vegas Summer League offers fantasy basketball's faithful their first honest look at the NBA's newest generation — a proving ground where potential meets professional scrutiny. In 2025, analyst Dan Titus emerged from opening weekend with a considered verdict: this rookie and sophomore class carries unusual depth, from Cooper Flagg's precocious playmaking to Alex Sarr's record-setting rim protection. The challenge, as always, is distinguishing those ready to contribute now from those whose value must be held in trust, cultivated across seasons rather than harvested in a single draft.

  • Cooper Flagg ran an NBA offense with the composure of a veteran, cementing himself as a near-certain top-100 fantasy asset before the regular season has even begun.
  • Alex Sarr shattered a Summer League blocks record with eight rejections in a single game while shooting nearly 50% from the field — a rare combination of defensive anchor and offensive promise.
  • Players like Kyle Filipowski and Liam McNeeley dominated Summer League statistically, but their fantasy value remains frozen until NBA rotation spots are confirmed.
  • Dynasty investors face a layered puzzle: Jaylon Tyson's 20-point, 12-assist double-double signals elite upside, while Nique Clifford's multi-category production is bottled behind Sacramento's veteran roster.
  • The broader tension of the weekend was clarity versus patience — some prospects are ready to be drafted now, while others demand the longer faith of a dynasty stash.

Las Vegas in July is where fantasy basketball players go to separate hope from evidence. Dan Titus spent opening weekend of the 2025 NBA Summer League doing exactly that, and what he found was a class with genuine depth across every format.

The most immediate takeaways centered on two players. Cooper Flagg, Dallas's versatile forward, ran point guard responsibilities with a composure that felt years ahead of his experience, making him a near-lock for the fifth round or earlier in most drafts. Alex Sarr of Washington made an equally forceful impression — setting a Summer League record with eight blocks in one game while shooting 48 percent from the field across two appearances, suggesting his offensive development is ahead of schedule. Both project as top-100 fantasy assets.

Several other names surfaced as legitimate late-round targets. Isaiah Collier delivered steady assist production for Utah. Jaylen Wells averaged over 20 points per game for Memphis with a well-rounded stat line, and if he locks down a starting role, he becomes a deep-league asset. Matas Buzelis drew 20 free throws across two games for Chicago — a sign his scoring profile may be evolving in year two.

Not every standout is fantasy-ready. Kyle Filipowski averaged over 29 points per game for Utah and drew Lauri Markkanen comparisons, but rotation clarity is needed before he becomes draftable. Rob Dillingham impressed as a distributor rather than a scorer, and Tre Johnson showed natural offensive instincts that could make him a waiver wire find mid-season.

For dynasty investors, the deeper names carry the most intrigue. Liam McNeeley surprised with 8.5 rebounds per game for Charlotte. Nique Clifford flashed multi-category appeal in Sacramento, though the Kings' veteran roster may delay his arrival. Jaylon Tyson looked almost overqualified for Summer League, posting a 20-point, 12-assist double-double while averaging strong numbers across the board — turnover concerns aside, the upside is hard to ignore. The weeks ahead will reveal which of these players become draft targets and which become the dynasty sleepers worth holding in quiet faith.

Las Vegas in July means one thing to fantasy basketball players: the first real glimpse of how the NBA's newest talent will translate to the professional game. Dan Titus spent the opening weekend of the 2025 Summer League watching dozens of prospects, and what he saw was a cohort of players worth serious attention across every format—from redraft leagues to dynasty stashes that could pay dividends for years.

The clearest takeaway was that Cooper Flagg, the Mavericks' forward, has already arrived. Titus watched Flagg shoulder point guard responsibilities with a composure that suggested he'd been running an NBA offense for years. His willingness to facilitate, combined with his versatility, makes him a near-certain lock to hear his name called by the fifth round of most drafts this season. Equally impressive was Alex Sarr of the Wizards, whose combination of rim protection and lateral mobility stood out immediately. Sarr set a Summer League record with eight blocks in a single game and shot 48 percent from the field across two appearances—a sign that his offensive game is developing faster than expected. For a player who will start and anchor a defense, that efficiency matters. Both players project as top-100 fantasy assets in 2025.

Beyond the obvious names, several other prospects emerged as legitimate draftable commodities. Isaiah Collier, Utah's starting point guard, delivered exactly what scouts anticipated: 12 points, 5 rebounds, and 8 assists per game over three games. His efficiency will fluctuate, but for teams hunting late-round assists at a discount, he's a viable target. Jaylen Wells of the Grizzlies, stepping into a larger role with Desmond Bane sidelined, averaged over 20 points with four rebounds, three assists, three three-pointers, and 1.5 steals per game. If he secures a starting spot and 30-plus minutes, he becomes a deep-league asset. Matas Buzelis, the Bulls' forward, showed improved physicality and drew 20 free throws across two games—a development that could reshape his scoring profile in year two.

Then there were the performers who dominated Summer League but aren't yet fantasy-ready. Kyle Filipowski, a second-year pro with the Jazz, looked like a future All-Summer League selection, averaging 29.3 points, 7.6 rebounds, 2.3 assists, and 3.3 three-pointers per game. Titus saw shades of Lauri Markkanen in his game. Terrance Shannon Jr. of the Timberwolves, fresh off playoff minutes, torched opponents while averaging 22 points, 6 rebounds, and 6 assists in two appearances. Rob Dillingham impressed not as a scorer—that was already known—but as a distributor, averaging 7.5 assists and potentially positioning himself as a meaningful rotation piece behind aging point guard Mike Conley. Tre Johnson emerged as the Wizards' most natural offensive weapon, a walking bucket who could surface off the waiver wire by midseason if the team makes the expected roster moves.

For dynasty investors, the real intrigue lies deeper. Liam McNeeley, a late first-round pick by Charlotte, proved to be the Hornets' most consistent performer and surprised with his rebounding—8.5 per game for a guard. Nique Clifford of Sacramento flashed multi-category appeal with 18.3 points, 6.3 rebounds, 3.7 assists, 2.3 three-pointers, and 2.0 steals per game, though the Kings' veteran roster may delay his immediate impact. Jaylon Tyson, the Cavaliers' 24th overall pick from 2024, looked almost overqualified for Summer League competition, posting a 20-point, 12-assist double-double against Indiana while averaging 19 points, 6 rebounds, and 6 assists. His turnover rate needs work, but the upside is undeniable. As the dust settles on opening weekend, the message is clear: this class has depth, and the next few weeks of Summer League will determine which of these players become draft targets and which become dynasty sleepers waiting for their moment.

Why does Summer League matter so much to fantasy players? Isn't it just preseason?

Model

It's the first time you see these players in a real NBA context—real spacing, real pace, real competition. You get to see who's actually ready and who's still a project. That changes draft strategy.

Inventor

Cooper Flagg running point guard duties—is that surprising?

Model

Not really, given what scouts knew about his skill set. But seeing it live, seeing the composure, that's different. It confirms he's not just talented; he's ready to contribute immediately in multiple ways.

Inventor

Alex Sarr's efficiency seems high for a defensive specialist.

Model

That's the thing—he's not just a rim protector. If he can shoot 48 percent and block eight shots in a game, he's not a one-dimensional player. That's what makes him top-100 material.

Inventor

Kyle Filipowski averaged 29 points but isn't draftable yet. Why?

Model

Playing time and role clarity. Summer League is a showcase. You don't know if he'll get 20 minutes or 35 minutes once the season starts. That uncertainty keeps him off draft boards until the regular season begins.

Inventor

What about the dynasty guys—are they worth reaching for?

Model

Jaylon Tyson and Nique Clifford have real multi-category appeal. If you're in a dynasty league, you're thinking three, four years out. These guys could be rotation staples by then. The risk is lower because you're not counting on them day one.

Inventor

So what's the biggest lesson from this Summer League?

Model

Depth. This class has it. There are draftable players, there are waiver-wire guys, and there are long-term holds. You don't need to panic draft. The talent is there at multiple levels.
