The 76ers will start twin towers Wednesday night against the Toronto Raptors at the Wells Fargo Center.
Joel Embiid will line up at power forward and Jahlil Okafor will play center when the Sixers are on offense. On the other end, the 7-foot-2, 275-pound Embiid will be closer to the rim. The 6-11, 265-pound Okafor will switch to power forward on defense.
Point guard Sergio Rodriguez, shooting guard Gerald Henderson and small forward Robert Covington will join the duo in the starting lineup.
"It's a responsible decision, defensively. It's stuff that we talked about a long time," Sixers coach Brett Brown said of starting the two centers. "It's my job to grow our program, grow our guys, and see what we actually have.
"We have really yet to see Jahlil and Joel together in any significant timeframe. Tonight, it's available. So I'm going to do it."

Embiid slid over to power forward when the Sixers used twin towers in this season's two meetings with the Orlando Magic.  He lined up at that position during Tuesday's practice and Wednesday's shootaround.

"I've been shooting pretty well. So I guess that's one of the reasons," Embiid said of why he's playing power forward as opposed to the 6-11, 265-pound Okafor.

The Sixers employ twin towers lineups only against bruising front lines, hoping for the best matchup. They don't want to pair them up against teams with mobile power forwards capable of shooting three-pointers. The Raptors have a 7-foot center in Jonas Valanciunas and 6-10 power forward in Pascal Siakam.

"I think no disrespect to Siakam, but he's not as good as a shooter," Embiid said. "That sets me kind of free to like play all over the place, helping off [Raptors shooting guard DeMar] DeRozan, Valanciunas. So it just kind of gives me free range to just play."
