The set-up: The Philadelphia 76ers and Boston Celtics open their seven-game series tonight at TD Garden and missing will be Bill Russell, Wilt Chamberlain, Larry Bird, Julius Erving, Kevin McHale, Hal Greer, John Havlicek and Billy Cunningham. The point being, it's a new day and new time in this rivalry. The Process" is no longer a punch line, as the 76ers won their final 16 regular season games and then eliminated the Heat handily in teh first round of teh 2018 playoffs, 4-1. As for the Celtics, the era of Pierce, Garnett and Allen had come to an end when Brad Stevens took over in 2013-14, with the Celtics going 25-57.However, that season was no more than a speed bump, as "Butler Brad" has Boston back among the Eastern Conference elite, despite battling key injuries. The Celtics needed everything they had to survive a seven-game, first-round series with the Milwaukee Bucks and their reward is an Eastern Conference semifinals matchup with one of the hottest teams in the league in the rested Philadelphia 76ers.

Philadelphia: The Sixers eliminated the Heat back on April 24 and the extra rest cannot be a bad thing for star center Joel Embiid, who returned from an orbital fracture to play the final three games of the series with the Heat. He averaged 18.7 points and 10.3 rebounds in those three games and shot 8-of-14 from the floor in Game 5. JJ Redick was Philadelphia's top scorer versus the Heat with 20.0 PPG but rookie PG Ben Simmons was nothing short of "special" in his first-ever postseason series, averaging 18.2-10.6-9.0 and 2.4 steals. The Sixers have waited through years of tanking to get back to respectability and now get their latest shot at their long-time rivals.

Boston: The Celtics rose to the challenge of a Game 7 (nothing new there) against the Bucks this past Saturday, shooting 53.6% in a 112-96 win. However, the big question heading into Game 1 of this series will be the status of shooting guard Jaylen Brown, who left the clincher against Milwaukee due to a hamstring injury. Brown had been Boston's top scorer through six games and hopes to not miss any time. "I was told that if we got in a pinch that he could play," head coach Brad Stevens told reporters after the win. "We decided that that was not going to happen. With hamstrings, let's see how he feels tomorrow." Brown averaged 17.9 points against the Bucks (also 4.7 RPG), just a shade behind Horford's 18.1 PPG (and team-high 8.7 RPG). Three others also average in double digits in Rozier (17.6-4.3-6.7), Tatum (15.4 & 5.3) and Morris (13.3 & 4.9).

The pick: This is the NBA's top rivalry in terms of series played. The teams meet for the 20th time in what has always been the Celtics but also been the Syracuse Nationals/Philadelphia Warriors/Sixers. The rivals last met in the playoffs in 2012, when Boston won a conference semifinals matchup in seven games.However, as noted above, that was then and this is now! The Celtics won three of four meetings during the regular season, including a matchup in London on Jan. 11. No many could have imagined at the start of the 2018 playoffs that Boston would have been a home dog against the 76ers in a Game 1 matchup at Boston. Make Boston a 10* play.
