Joel Embiid and Ben Simmons shined again, and the dominant duo ushered the nightmares-into-dreams Process of the Philadelphia 76ers into the second round with a 104-91 win over the Miami Heat on Tuesday night.

The 76ers, winners of 10 games just two seasons ago, are in the second round of the Eastern Conference playoffs for the first time since 2012.

"[I'm] proud of all of us for staying together," coach Brett Brown said of the Process to build these 76ers. "We didn't pivot out of what we said we were going to do, and I think slowly we're reaping the benefit of that."

The Sixers won the series 4-1 and turned the Wells Fargo Center into the wildest house party in the city.

"I kind of promised the city this," Embiid said.

Embiid had 19 points and 12 rebounds, Simmons had 14 points and 10 boards, and the entire team had everyone dancing along for the ride.

"We've got more to do. We've got more to give," Brown said.

Boston 92, Milwaukee 87: Al Horford had 22 points and 14 rebounds, Marcus Smart made an impact in his first game since mid-March and the host Celtics beat the Bucks for a 3-2 lead in their series.
