Celtics vs. 76ers – 1 p.m. ET, ABC Boston stuck with its trusted unit of Derrick White, Sam Hauser, Jaylen Brown, Jayson Tatum and Neemias Queta for Game 1, a grouping Joe Mazzulla has rolled with since Tatum’s return from injury. Philadelphia countered by announcing Tyrese Maxey, rookie VJ Edgecombe, Kelly Oubre Jr., Paul George and rookie center Adem Bona as its starting five, with Joel Embiid still out after appendix surgery. Quick hits • DFS spotlight: Edgecombe’s two-way role (18.6 PPG, 6.8 RPG) at shooting guard makes him a low-owned upside play against Boston’s switch-heavy defense. • Betting nugget: The Celtics have won six straight postseason series against Philly dating to 1985. Suns vs. Thunder – 3:30 p.m. ET, ABC While Oklahoma City’s starters (Shai Gilgeous-Alexander, Dillon Brooks, Jalen Williams, Chet Holmgren, Ivica Zubac) stay intact from their title run, Phoenix will ride Devin Booker, Jalen Green, Mikal Bridges, Keegan Murray and Deandre Ayton, the same lineup that drilled 18 threes in the Play-In finale. Magic vs. Pistons – 6:30 p.m. ET, NBC/Peacock Detroit’s 60-win core of Cade Cunningham, Ausar Thompson, Isaiah Livers, Jalen Duren and Isaiah Stewart is intact after Cunningham’s return from a collapsed lung.

Trail Blazers vs. Spurs – 9 p.m. ET, NBC/Peacock Victor Wembanyama makes his playoff debut alongside De’Aaron Fox, Stephon Castle, Jeremy Sochan and Zach Collins for San Antonio.

Why today’s starting lineups matter 1. Minutes = Money: Playoff rotations tighten, so starters like Hauser or Bona, who see a bump from 20 to 30 minutes, become salary-savvy DFS pieces. 2.

Prop angles: Holmgren’s blocks prop (2.5) is in play against a Suns squad that attempts the league’s second-most shots in the paint.
