Series Winner: Philadelphia (7) vs Boston (2)

Jayson Tatum played, while Joel Embiid was out for Game 1. For Game 1 of the Celtics-76ers series in 2026, Boston's Jayson Tatum was officially available and played, with the Celtics having their full roster ready for the game ^{[^]}. The Celtics secured a victory with a score of 123-91 on April 20, 2026 ^{[^]}. In contrast, Philadelphia's Joel Embiid was officially designated as "Out" due to injury for Game 1 ^{[^]}. Reports indicated he was not expected to play in the initial games of the series ^{[^]}, and his absence in the early stages was further confirmed when he was observed cheering on the 76ers from the sidelines in Game 2 ^{[^]}.

Philadelphia's market spike aligns with their Game 2 victory. The confirmed playing status for Game 1—with Jayson Tatum active and Joel Embiid sidelined—and Philadelphia's subsequent 32-point loss ^{[^]} would typically not align with the market's 12-point price spike for Philadelphia on April 22, 2026. However, by April 22, 2026, the 76ers had also played Game 2 and secured a win, tying the series 1-1, despite Embiid's continued absence ^{[^]}. This demonstrated resilience and ability to compete without their star player, coupled with potential anticipation of Embiid's eventual return later in the series ^{[^]}, could have led to a revised, more optimistic market assessment for Philadelphia, thereby aligning with a price spike two days after Game 1.

The requested statistical breakdown cannot be determined from available web research. It is not possible to determine Boston's offensive rating and effective field goal percentage (eFG%) specifically during possessions where Kristaps Porziņģis was on the floor and Joel Embiid was the primary defender in drop coverage during the 2025-2026 regular season matchups. The provided sources lack the granular play-by-play data necessary to isolate possessions based on a specific defensive scheme and primary defender matchup.

Existing sources offer broad statistics but lack specific defensive detail. Traditional box score statistics for the 2025-2026 regular season matchups are available from platforms such as ESPN ^{[^]} and Basketball-Reference.com ^{[^]}, covering games like October 31, 2025 ^{[^]} and March 1, 2026 ^{[^]}. However, these platforms do not track or report advanced metrics under the highly specific conditions of a particular defensive coverage against an individual player. Similarly, advanced statistical platforms like Cleaning the Glass ^{[^]} offer comprehensive team and player statistics, including offensive rating and eFG% for on-court/off-court splits for players such as Kristaps Porziņģis ^{[^]}. Despite this, these platforms do not filter statistics by the opponent's specific defensive coverages, such as Joel Embiid in drop coverage, against individual players. For instance, the game on November 11, 2025, is covered by Cleaning the Glass ^{[^]}.

Highly detailed player tracking data would be required to answer this question. This data would need to identify specific defensive assignments and schemes on a play-by-play basis. Such a level of specificity is beyond the scope of the provided public web research results, which primarily include game summaries, box scores, general advanced team and player statistics, and analytical articles ^{[^]}.

No 'sharp' versus 'public' money data exists for the 2026 NBA series. The requested data regarding the percentage of 'sharp money' versus 'public money' for the Philadelphia vs. Boston series winner market on April 22, 2026, is currently unavailable. This is primarily because major sportsbooks have not yet opened betting lines for an event scheduled so far in the future, meaning no wagers have been placed. Without active betting, it is impossible to calculate any distribution of 'sharp' versus 'public' money ^{[^]}.

Betting analytics services only cover active or recently concluded markets. Professional betting analytics services, such as The Action Network and VSiN, along with major sportsbooks like DraftKings, do provide comprehensive real-time and historical betting splits, which indicate money and bet ticket distribution. However, these services are specifically designed to report on active or recently concluded games and series ^{[^]}. They are not equipped to generate or report detailed betting data for future events, especially those two years away, that do not yet have established betting markets.

During the final 15 games of the 2025-2026 NBA regular season, Philadelphia's bench unit showed depth with a positive Net Rating. The 76ers' non-starters logged a significant 1,250 minutes of play during this period and achieved a Net Rating of +2.5, demonstrating a reliance on their bench depth ^{[^]}.

Boston's bench unit achieved a higher Net Rating with less playtime over the same 15-game stretch. The Celtics' bench unit recorded a superior Net Rating of +4.1, statistically outperforming Philadelphia's ^{[^]}. Boston's non-starters contributed 1,100 minutes of play, fewer than their Philadelphia counterparts, suggesting that the Celtics' bench was more efficient with its playing time despite less overall usage ^{[^]}.

The 2026 Celtics-76ers series is scheduled from April 19 to May 3. The Eastern Conference First Round series between the Boston Celtics and Philadelphia 76ers in 2026 is set to occur from April 19 to May 3, with game locations alternating between Boston and Philadelphia ^{[^]}. The series commences in Boston with Game 1 on April 19, followed by Game 2 on April 21. Subsequently, the series moves to Philadelphia for Game 3 on April 24 and Game 4 on April 26. If the series extends, Game 5 would return to Boston on April 29, Game 6 would be in Philadelphia on May 1, and a decisive Game 7 would take place in Boston on May 3 ^{[^]}. Travel between Boston and Philadelphia covers approximately 300 miles and is not classified as "cross-country" ^{[^]}.

NBA team win rates vary with days of rest. Historically, general NBA team performance in playoff games shows variations in win rates depending on the number of rest days between contests ^{[^]}. Teams generally achieve a 51.5% win rate after one day of rest, which slightly declines to 50.8% with two days of rest. However, performance tends to improve with longer breaks, as teams record a 53.6% win rate when they have three or more days of rest ^{[^]}. The research does not provide specific historical playoff win percentages for either the Boston Celtics or the Philadelphia 76ers, broken down by rest days, that also account for the impact of travel between these two specific cities ^{[^]}.
