The 76ers plan to give Joel Embiid a day off periodically to rest. The first one came Monday, three days into training camp.

But Embiid did participate in a post-practice one-on-one drill against a staff member, along with Dario Saric.

"We had two great days and tomorrow he'll come in, and it's sort of a game day for us," Sixers coach Brett Brown said in reference to the Blue and White scrimmage at 7 p.m. Tuesday at the Palestra. "We'll come in, have a shootaround, then go to the Palestra and play in front of a fantastic crowd. We just felt like, let him have today to rest and we're going to jump back into it tomorrow."

The star center has no playing-time restrictions and is healthy. However, Brown noted Sunday that the team will take advantage of its camp bodies to keep him fresh for the coming season. The Sixers have five centers on their preseason roster: Embiid, Amir Johnson (forward/center), Mike Muscala (forward/center), Emeka Okafor, and Norvel Pelle.

An all-star and second-team all-NBA selection, Embiid averaged 22.9 points, 10.9 rebounds, 3.1 assists, and 1.76 blocks in 63 regular-season games last season. He finished sixth in the league with a 99.7 defensive rating.

Muscala impressing Brown

The Sixers acquired Muscala from the Atlanta Hawks this offseason in a three-team trade that also included the Oklahoma City Thunder.

He comes to the Sixers with career averages of 5.4 points and 3.1 rebounds in 243 games, with 18 starts, over five seasons. He also has shot 37.8 percent on three-pointers, including a career-best 41.8 percent two seasons ago.

"When I see him run the floor now that he's under our roof, I think that his versatility and his ability to switch [on defense] is better than I thought," Brown said. "He's long, like he's got a bounce."

Would Butler fit in?

It's no secret that the Minnesota Timberwolves are shopping disgruntled swingman Jimmy Butler. Like most teams, the Sixers inquired about the four-time all-star. While a great player, Butler has had his chemistry issues with young teammates in Minnesota and with the Chicago Bulls.

Brown said the intel he receives has some influence on how the Sixers proceed in attempting to acquire someone in a trade. But he added that you can't be intimidated.

"I feel like this program, the culture is almost there where it's strong enough to be able to invite somebody in and show them this is how we do things, whoever that might be," the coach said. "So it's all on the table.

"But it's certainly, I suppose, in some ways like analytics: It doesn't always force decisions. It really doesn't."
