Not every team has or even needs someone calling out defensive plays, but it can help a team play better defense.

Jokic? Doesn't seem like the right personality.
Millsap? Seems to have the defensive side of the ball down but is he one that will direct everyone? I hope so.

Lyles? Not sure
Lydon? Perhaps not as a rookie, but down the road? Not sure
Hernangomex? Probably not
