He’s playing with the MVP
Playing with Joel can help your Assist numbers, I don't know how Embiid helps your scoring and shooting numbers, or limits your turnovers.. The Guard taking maxey, is not collapsing on Embiid. They are not running switch pick and roll where Embiid should get huge credit for Maxey points,,
Maxey scores making 3s, and pushing tempo on fast break.. That is why him and Fox are comparable..
If you want to make an argument for what you said, state Tobias Harris fast start.. But then you have to talk that any other option is Melton/Oubre and then Paul Reed, Washed Covington (offensively), Tatum (about to retire)....
Meanwhile, Fox has Sabonis (a really good offensive big), Monk (great offensively), Duarte, Huerter.. All solid offensively.. Their offensive teammates are extremely comparable to me (and I welcome an argument for anyone to say supporting staff, that Sixers are significantly better then Kings.. Other then a simple Embiid>>> all players in NBA except Giannis and Jokic)
