I still question how all three of Simmons, Fultz, and Embiid will fit together. This is especially true if Fultz doesn’t get his shot back, as it’d be really difficult to play Simmons and Fultz together if neither of them space the floor.
If Futz is 100% that means he's got his shot back. In that case, Simmons, Fultz and Embiid should be a great fit. The Sixers were at the bottom of the league in running pick and rolls because of Simmons inexperience at playing PG and limitations. A 100% Fultz should be excellent at running pick and rolls which will be a big plus for Embiid and the Sixers offense.
I didn't believe that Fultz was the clear best player in his draft or a franchise talent player and I still don't. I think his upside is Kyrie but that he has a pretty high floor. A starter level poor man's Kyrie would be a very nice player for the Sixers.
