Joel Embiid conceded that the 76ers did not play their best basketball in their playoff series loss to the Celtics, but he agreed with Ben Simmons' assertion that the duo will win "a lot of rings."

The 76ers' hopes of reaching the Eastern Conference finals were dashed in Wednesday's thrilling 114-112 Gam 5 defeat, despite Embiid and Dario Saric each contributing 27 points to the cause.

There were high hopes for the 76ers heading into the NBA playoffs after a regular season that yielded 52 victories and a first playoff series victory since 2012 — a Round 1 triumph against the Heat.

It did not pan out quite as the 76ers had hoped, but Embiid insists the future is bright for a talented and youthful Philadelphia team.

Speaking about a moment where Simmons approached him with his empty hands, Embiid said: "He was like, 'There's going to be a lot of rings on these.'

"We have a bright future. We're going to be fine.

"I feel like we had more [to show]. We got a lot of talented guys; we didn't play our best.

"We feel like when everybody is on, we're unbeatable. We committed a lot of mistakes [in the series]. We've got to learn from it."

Simmons echoed those sentiments, but the Australian believes he can take a lot of positives from the series.

"The feeling right now is I didn't want to be done. I feel like I had a lot more to go," he said.

"I'm just learning, this is just the start for me, I have a long way to go. So, second series and I'm learning, there's a lot of things I learned this series that I didn't against Miami so that makes me a better player, so I'm grateful for those opportunities."
