Contact with elbow

[Junker]

In the original post the player was swing their elbows, not intending to contact anyone. My question is what purpose is there of swinging the elbows if not to contact someone and keep them off? It is one thing if a player holds the ball high with their elbows out (fundamentally sound if you ask me) and catches someone with an elbow as they pivot, but if they contact someone with an elbow when they are merely swinging their arms, I have a common foul.
