Horford finished with 26 points while Tatum added 28 points as Boston surged into a 1-0 lead in the best-of-seven series with a statement victory.
The Celtics, who had trouble finding consistent offense in their first-round series against an inferior Milwaukee Bucks' defense and recently lost their leading scorer from that matchup, Jaylen Brown, were expected to struggle to produce points against a stingier Sixers team. Furthermore, the Sixers are unlikely to continue to shoot as poorly as they did Monday - 19.2 percent from 3-point range - and the Celtics probably will regress a bit after shooting the lights out in Game 1.
Ben Simmons (No. 25) of the Philadelphia 76ers defends Shane Larkin of the Boston Celtics during the second half of Game One in Round Two of the 2018 NBA Playoffs at TD Garden in Boston, Massachusetts.
His Philadelphia 76ers were nearly literally run off the court by the Boston Celtics in Game 1 of the Eastern Conference Semifinals on Monday night.
"There was some concern that I could re-aggravate it and it becomes a season-ending injury", he said.
"I love when people talk trash", Embiid said. "We're going to have to fix some things". A six-day break can be used to somewhat explain this, but it's not like Philadelphia got jumped and were forced to play catchup.
"I was saying last night that Philly and Boston, with the youth of the guys, they have a chance to make this a generational-type thing. I never thought we were in the game", Brown said.
But as the Celtics have shown all year, regardless of who they have on the floor, they'll be a match for any team. "I think our fans our louder than that so I mean, it was OK". Redick is an above average defender, but he's more suited to guard players his own size, which is why Brown will likely adjust by moving him onto Smart. It sure felt like we were playing a good team today.
"Give [the Celtics] credit".
Sixers: Embiid is the first Sixer with 30 points in a playoff game since Andre Miller in 2009. "I personally grew up with this rivalry, just right on your doorstep and just a big part of your basketball life as a young kid".
Simmons actually looked like a rookie in Game 1.
