I have no problem with Simmons on ball as he got the defense to bend. He just has to make his move a lot quicker. The Sixers moved the ball around and got Simmons a wide open look after he create the initial openings. But since he can't shoot the D just sank off him causing Sixers to reset. I think they just need to leverage Simmons iso as a way to get Joel a post touch and Simmons to make his move much faster. Either way this is definitely attributed to growing pains and learning how to close as a team.
Nah, he honestly can't be on the ball in that situation, his reluctance to shoot just kills things. It's hard to get Joel iso's when Simmons is the passer because his man immediately doubles off him when he passes it to JoJo. They honestly need Fultz to get right, drafting him was for moments like this.
