Content Layer: Boston Bricked the Greatest Closeout Window in Franchise History
Two hours before tipoff Boston announced Jayson Tatum out with left knee stiffness — the same knee, not the surgically repaired Achilles. Joe Mazzulla started Derrick White, Jaylen Brown, Ron Harper Jr., Luka Garza and Baylor Scheierman. Sam Hauser and Neemias Queta benched in a Game 7. Philadelphia opened the night on a 9-0 run and led 32-19 after the first quarter. The Celtics led at one point in Q2 (37-36), but the Sixers closed the half on Embiid blocks of Brown and White at the buzzer for a 55-50 lead.
The third quarter was the structural break. A Paul George trey, a Maxey pullup and a 20-year-old VJ Edgecombe three made it 84-66 — an 18-point hole entering Q4. Boston ripped a 9-0 run to open the fourth, then a Brown three-point play cut the lead to 92-91 with 8 minutes left. Then the rims came alive: 10 consecutive missed shots in the final five minutes. Philadelphia pulled away to the 109-100 final.
Joel Embiid logged his first Game 7 win — 34 points, 12 rebounds, 6 assists on a deep-rotation injury list. Tyrese Maxey went 30 / 11 / 7 on 11-of-20 in 45 minutes, repeatedly attacking Boston's switches. VJ Edgecombe, the 20-year-old rookie, dropped 23 on 8-of-17 (5-of-11 from three) with 6 rebounds and 4 assists. Paul George, listed questionable due to illness, played both ends for 13 quiet points. The Celtics shot 13-of-49 from three (26.5%) — making it 57-of-80 threes missed across Games 6 and 7.

Probability Matrix: Round 2 NYK vs PHI
Bravsen model basis: NYK home court (#3 vs #7 seed), 2-day rest advantage (NYK closed Apr 30, PHI closed May 2), Embiid post-appendectomy load management, Maxey-on-Brunson defensive matchup, NYK perimeter depth (Anunoby, Bridges) vs PHI three-point gravity (Edgecombe 5-11 outlier weighted), Towns-Embiid frontline split. Note: our Game 7 prior model called BOS 60% — reality reversed on Tatum DNP, Q3 PHI break, and BOS 3PT collapse. Round 2 estimates incorporate updated PHI shooting profile and full-roster availability.
Link Layer: The Fallout
56-win regular season, second seed in the East, gone in seven games to the seventh seed. The first 3-1 collapse in franchise playoff history. Tatum's knee stiffness opened the door; Mazzulla's Game 7 starting lineup (Garza, Harper Jr., Scheierman) didn't close it. The 26.5% three-point night caps two months of identity questions about a team that built its season around Tatum's post-Achilles return. Joe Mazzulla's job security, Brown's usage in Tatum-out scenarios and the Hauser/Queta benching are now full-summer storylines.
The 13th NBA team in playoff history to come back from 3-1 down. Maxey-Edgecombe is the most efficient backcourt of the East playoffs through Round 1: Maxey averaged 28.5+ PPG, Edgecombe's 23/5/4/6 at 20 years old in a Game 7 reads as a generational outlier. Embiid's 34/12/6 in his first career Game 7 win at 17 days post-appendectomy reframes the durability narrative. Nick Nurse out-coached Mazzulla in the closing three games. Round 2 starts on two days rest at MSG.
The Knicks have been waiting since Thursday April 30 after the 140-89 close-out of Atlanta. Mike Brown gets two days' rest advantage over Philadelphia, home court for Games 1-2 at Madison Square Garden, a healthy Anunoby on a 4-of-6 Game 6 three-point night, and a Towns coming off back-to-back triple-doubles. PHI arrives with an emotional ceiling on May 2 in Boston and a backcourt that just played 45+ minutes each. The bracket compression now favors New York at every margin except Embiid in transition vs Towns in the pick-and-roll.
