I don’t think too many players is the problem (would be a nice problem to have though). Saric does have a somewhat similar skill set to Simmons but he’s not a particularly good ball handler and he’s a better shooter. The hope is that he develops into a stretch 4- he’s ok at that but needs to improve his 3 pt shooting. He’s also a good rebounder, especially on the offensive boards.
So to an extent, yeah, they’re not maximizing Dario’s skill as a passer but given that Brown emphasizes ball movement his passing should work itself into the offense as things get smoother. I think Fultz will be playing off the ball more when he gets back. If he cracks the starting lineup you might see Dario on the second unit, although I think I’d rather see him start and move Covington to the 2nd unit.
TJ’s improvement as a shooter this season has been dramatic. It’s still not pretty but he’s becoming a fairly reliable scorer off the bench.
