Coaching in basketball is way different than football. The head coach sets the philosophy and style of play on both the offensive and defensive end and assistants execute the vision, they're not like a Kwiatkowski who we know is going to be bringing in his defense. That's part of why the Clippers are willing to hire Ty Lue after canning Doc Rivers, Lue wasn't responsible for the offensive style and it's changed (a bit) under him. There are some exceptions like a Yaklich, but even that is blended into the head coaches style to a degree. All we can really know about assistants are who they coached under which may influence how they think, who they are leads for recruiting, and maybe a positional group they specialize in working with which can also be fluid. I'm surprised more teams haven't brought in specific shooting coaches though, there's plenty that work with NBA players independently and if you have a guy fixing players forms I'd think that's probably the biggest advantage you could get in the college game. Someone can be free to correct me though if I'm speaking from my ass on any part of this.
