I have seen many other teams use their big man to throw the inbounds pass. Some big men are very good at throwing that first pass. I’ve seen some big men throw the home run pass that went over the press into the other backcourt for an easy layup! And on the other hand I’ve seen guards being used to throw in bounds passes and teams struggling because the players don’t get open or know what to do with the ball once they receive it and the team’s best ball handler was the guy throwing the inbounds pass.
