I think you could say the same thing about Embiid (assuming he gets in better shape). Surround him with good three point shooters, instead of Butler and Simmons. Imagine a world where they did nothing this season, except trade Simmons this summer for someone who can make a three-pointer.
2019–2020 76ers: Embiid, Redick, Covington, Saric, Shamet, Bridges + Simmons trade.
Better yet, imagine Embiid playing in San Antonio at the 6th slowest pace in the NBA.
