Celtics Beat Episode 665: Celtics Miss Out on 40/20. Can Boston Make HISTORY? w/ Dan Greenberg

Date: February 26, 2026
Host: Adam Kaufman (with Evan Valenti)
Guest: Dan Greenberg (Barstool Sports, aka “Barstool Greeny”)

Episode Overview

This episode dives deep into the Boston Celtics’ failure to achieve the coveted “40/20 rule”—a historical benchmark for NBA title contenders—while assessing what it means for their championship hopes. Adam Kaufman, Evan Valenti, and Dan Greenberg engage in a rich discussion on the significance of 40/20, dissect alternative contender credentials, and debate the impending return of Jayson Tatum following his Achilles injury. The episode also explores award races (Coach of the Year, MVP), the Celtics’ latest loss in Denver, and what the road ahead looks like with Tatum’s return on the horizon.

Key Discussion Points & Insights

1. The 40/20 Rule and Why It Matters

• Definition: Win 40 games before your 20th loss in an 82-game NBA season. Credited to Phil Jackson, this is viewed as a hallmark of legitimate title contention.
• Historical Weight: Over the past 44 seasons (excluding shortened years), 40/20 teams won the NBA title 40 times; only four exceptions. Typically, 3–5 teams per year qualify.
• Celtics Context: Boston missed out by a single game (ended up at 38–20 after losing to Denver), ending realistic 40/20 hopes.
• Greenberg’s Take:

  “I think people, once they didn't hit it... started to see a lot more of, ‘oh, this doesn't matter...’ No, if they had hit it, we would all be treating it like you normally would when, like, when they hit it in their title year, it was a pretty big deal.” — Dan Greenberg (05:51)

[04:16] Greenberg explains 40/20 does not guarantee a title but is a “very, very, very important box to check.”
[06:27] Beyond 40/20: Must also either have an SRS (Simple Rating System) over 4.0 (point differential + strength of schedule), and/or be a top 3 seed—NO champion in NBA history has failed to hit at least two of these three markers.

• Celtics Hope: They “missed” 40/20 but still check the other two boxes—making them similar to the ’94–’95 Rockets, who failed 40/20 but added Clyde Drexler midseason and won it all.

2. Why Some 40/20 Teams Don’t Go the Distance

• Experience Matters: Teams like this year’s Pistons, though 40/20, are young and have not won a playoff series before—history says teams without main guys who’ve made a Conference Finals almost never win it all ([09:32]–[11:11]).
• Recent Examples: Last year’s Cavs and earlier versions of “The Process” Sixers hit 40/20 but flamed out due to lack of deep playoff experience.

3. Does Missing 40/20 Really Hurt Boston’s Title Odds?

• Kaufman Pushes Back:

  “Do you really believe in your heart of hearts that if The Celtics started 40–19 versus... 40–20... they are less likely to win the championship?” — Adam Kaufman (11:11)

• Greenberg's Response:

  “Historically? Yeah... their probability takes a hit just per NBA history... This is why the regular season matters.” (12:11)
  Greenberg emphasizes that teams often “barely missing it” usually end up not winning, regardless of late-season momentum.

4. Who Are the True Championship Contenders? [16:21]

• Greenberg’s List:
  • East: Pistons, Celtics (plus maybe Cavs if Harden is healthy)
  • West: Thunder, (mini gap) Spurs. Nuggets hesitate due to missing 40/20 and injury questions.
• Skepticism about Rockets: Lacking Stephen Adams (offensive rebounding) and solid point guard play sinks their playoff viability ([16:56]).

5. The Awards Watch: Coach of the Year, Executive of the Year, MVP

• Coach of the Year:

  • Pistons’ J.B. Bickerstaff is favored; Joe Mazzulla is the clear second despite extensive adversity.
  • Celtics losing Tatum and still contending is historic, but criteria seem to shift yearly ([22:59]–[25:22]):

    “What more does [Mazzulla] have to do to finally win it if this season doesn't do it?” — Dan Greenberg (33:13)

  • Perception that Celtics coaches/executives are perennially overlooked for awards despite league-best winning rates since Brad Stevens’ arrival.

• Executive of the Year:

  • Some argue Phoenix’s reshuffling deserves Executive of the Year over Boston’s survival moves.
  • Stevens could sneak into contention due to the success and development of draft picks like Ugo, Walsh, Baylor, and managing the cap.

• MVP Watch:

  • Top candidates per odds: SGA, Jokic, Cade Cunningham. Jalen Brown on the fringe if SGA/Jokic/Wemby fail to hit the new 65-game minimum.

  • “There's no shame in coming in fifth in the MVP. Like, you were awesome that year, that's all.” — Dan Greenberg (66:19)

  • If Jalen Brown is to win, it’ll likely be due to “narrative” more than pure statistical dominance.

6. Jayson Tatum’s Imminent Return: Roster Chemistry & Caution [47:18]+

• Discussion: Theoretical risk of disruption to team chemistry and Jaylen Brown’s role upon Tatum’s return is overblown.
• Greenberg:

  "I’ve never doubted their ability to work together ... Tatum coming back would mean Jalen Brown gets less midrange jumpers? That doesn’t make any sense to me." (47:18)

• Minutes Management: Expect Tatum to be ramped up slowly (15–22 min early) but still playing his normal offensive role.
• Caution: Only real unknown is how Tatum’s body responds to game conditions ([51:43]). The only choice is to “see it” and adjust.

7. Celtics-Nuggets Recap & Big-Picture Takeaways [38:15]+

• Loss to Denver: A tired team, on a back-to-back, shot badly, but also exposed the playoff ceiling for the Celtics without Tatum against elite, physical defenses.
• Greenberg:

  "They ran out of gas... But I do not think you can overlook the fact we saw what this version looked like against a quality opponent and a quality defense." (40:16)

• Formula for Beating Jokic: Limiting his assists was the plan, but Celtics’ poor collective effort lost them the game.

8. When Will Tatum Return?

• Speculative Dates:
  • March 4 (vs Charlotte) and March 6 (vs Dallas) are the leading candidates. Earlier is better for ramp-up ahead of the playoffs ([59:34]).
  • The need for 5–6 game “runway” for re-integration before April.

9. Memorable Quotes & Moments

• “It’s just never going to be consistent [on awards voting]... It fits an area that just so happens to bypass Joe Mazzulla while he continues to win at a rate that no other team in the league is winning at.” — Dan Greenberg (27:44)
• “This is why the regular season matters. This is why being good in clutch situations matters.” — Dan Greenberg (12:11)
• "The only baskets you seem to be giving up are threes, you know, despite the opposing team not being able to make anything." — Dan Greenberg (43:07)

Summary: Tone, Flow, and Recommendations

The episode is rich in analytics-driven analysis, Celtics-centric hope, and candid perspective. Adam Kaufman balances optimism with historical skepticism, Dan Greenberg provides deep research and conviction on why certain NBA benchmarks matter, and Evan Valenti acts as the pragmatic fan voice. For Celtics faithful, this is both a sobering look at the team’s precarious path and a hopeful, narrative-driven defense: Boston can still make history, but they’ll need Tatum healthy, strong finishing form, and perhaps a bit of luck against the weight of NBA precedent.

For new listeners or those seeking a one-stop Celtics playoff prognosis, this episode offers both context and detail to understand the very real stakes for Boston’s stretch run—and what history says about their chances.
