It’s not about playing small ball. It’s about playing your best lineup. King at the 3 is not leveraging his talent. It is more likely mitigating it. You’re making King relatively less athletic and less skilled when at the wing.
For what gain? Likely worse defense and a more congested offense. King is playing the 4 on all those teams you listed.
You’re advocating for the opposite of CMC’s approach. Campbell isn’t forcing a player into a role that he’s not bust suited for. He’s not playing a guy that’s not best at TE just because one year we used 3 TEs and this player could kind of fill in. If he’s better as a Lazard type WR, he’ll be a WR. TJ isn’t playing a 6’8”F at the wing just because UNC had Manek and Bacot in the frontcourt and a wing that happened to be 6’8”. Remember, it’s players, formation, plays…which means putting King at the 4 we’re he’s best suited and working around that. It’s not formation, players, plays, match UNC’s lineup height
I think the players, plays, formations analogy is correct. But part of that is figuring out how to get your best guys on the floor/field. Just as football played a bunch of 3 tight-end sets over the last few years, I think it’s reasonable to assume that TJ will figure out ways to get Jaz and King on the floor at the same time (whether as 3-4 or 4-5) simply because both are too valuable to be sitting on the bench.
Granted, we don’t know what the roster is going to end up looking like, but I can’t see a future where they’re not both getting a ton of minutes.
