The Philadelphia 76ers eliminated the Boston Celtics 109-100 in Game 7 of the Eastern Conference first round on Saturday night at TD Garden, advancing to a conference-semifinal series whose opponent will be set Sunday [1]. Tyrese Maxey scored 32 points; Paul George added 24; Jayson Tatum, who suffered a Grade 2 hamstring strain in Game 5 on Tuesday, watched the entire game from the bench in a charcoal suit. Boston shot 9-for-31 from beyond the arc.

The paper walked the series into Saturday night under the second-apron architecture frame — the argument that Boston's salary-cap structure, which committed roughly $214 million in 2026-27 guarantees to a five-player core, left the team unable to acquire a credible Tatum replacement at the February deadline. The Game 7 result was the first postseason instance where that argument cashed in real losses. With Tatum out, the Celtics' shot-creation hierarchy collapsed onto Jaylen Brown (28 points, eight turnovers) and Derrick White (19 points, 6-of-15); the 39-year-old Al Horford logged 38 minutes; the bench produced 18 points on 6-of-19 shooting. The minutes line is the cap-architecture line.

The basketball decisions Brad Stevens did not make in February are the part the next month will analyze. The Celtics had a $14.2 million trade exception from the Holiday extension and the option to send a 2030 first-round pick and a young rotation piece in a deadline package; both were untouched. The reasoning, then and now, was that the second-apron restrictions on aggregating contracts in trade made any real upgrade prohibitive. Stevens's published explanation in March was "we built this team to win at full health." Saturday night was the cost of that bet [2].

The Maxey explosion is the basketball news. Twelve fourth-quarter points on six attempts, two pull-up threes from above the arc, the and-one drive at 4:38 that pushed the Sixers' lead from four to seven and forced Joe Mazzulla to burn his last timeout with three minutes still on the clock. Maxey is averaging 28.4 points and 7.1 assists in the series; his Game 7 plus-minus was +14. Paul George, in his first postseason for Philadelphia, had been dismissed through the regular season as a bad fit alongside Joel Embiid and Maxey; the playoff version has produced 21.8 points on 49 percent shooting and the defensive cover that allowed Maxey to gamble for steals. He had three steals in Game 7 and the corner three with 1:42 left that ended Boston's last serious push [3].

Embiid played 31 minutes with the right knee that has limited his postseason availability for three consecutive years; he scored 18 points on 7-of-15 and grabbed 13 rebounds. The minutes restriction is the structural piece for the next round — Philadelphia's coaching staff has spoken openly about a 30-32 minute target across a seven-game series. Whether Embiid's load can absorb the conference semifinal against either Cleveland or New York is the basketball question. The cap-architecture answer holds either way; the Sixers are, on Saturday's evidence, the conference's best healthy team [4].

The X framing of the result was the second-apron rule operating as designed and producing exactly the outcome the rule was written to produce. The 2024 collective-bargaining agreement that the league negotiated with the players' association introduced two apron levels and tied a series of competitive penalties to the upper apron — the bar against aggregating contracts, the inability to use the taxpayer mid-level exception, the loss of access to a traded-player exception, the freezing of a future first-round pick. The Celtics crossed the upper apron on the Holiday extension and the Porzingis re-sign in 2024; the deadline-day flexibility was the price. Saturday night was the bill [5].

The mainstream framing was the injury-and-Maxey story; the X framing was the cap-architecture story. Both are true. A reader who watches only the box score sees Tatum's hamstring; a reader who reads the cap sheet sees the rule that decided which way the hamstring tilted the series.

The Sixers' next opponent will be the higher-seeded survivor of the Cavaliers-Knicks series, which is at 2-2 with Game 5 in Cleveland on Sunday afternoon. The conference final, if Philadelphia gets there, will run against either Indiana or Milwaukee. The team that walked off the TD Garden floor Saturday night is the team the East was supposed to be, three years ago, before the cap rule changed.
