Dribbler

[beancenzo]

Hi, I've posted once before, and I am not an officiator.

I play with someone who does this:

While a player is dribbling the ball, the defender tries to either steal or tap the ball away (no infraction). The dribbler makes a fist with the non-dribbling hand and sticks that same arm out to prevent the player from getting closer. Contact between the two players is often made. Is this legal? Often, this move by the dribbler is more like a swing against the defending player. I got hit pretty hard a few times while playing (good) defense.
