So they could use a three man backcourt of Maxey, Melton and E.Gordon. Then have four forwards with Harden & T.Harris as starters and D.House & Niang as bench forwards. Embiid at center with Paul Reed as backup big.
That perimeter rotation is similar to the Rockets - Harden, E.Gordon, D.House. Then swapping Maxey and Melton in. That perimeter rotation is small-ish but it could work well next to Embiid.
I do believe Philly needs to trade Thybulle for a shooter. Can't play a non-shooter next to Embiid and Harden. Particularly Harden. They need shooters to open the floor for their one-on-one play. Eric Gordon would be a good addition for them.
Edit: Ah, I forgot PJ Tucker! Another solid forward & ex-Rockets player.
