The coral-shirt teammate stands behind and to the right. Interpretation: this appears to be preparation for a forearm pass. The still cannot establish contact, timing, weight distribution or the rally outcome."

Start with gentle tosses, adjust your feet to meet the ball, then send a controlled forearm pass toward that target. Try five passes and compare where they land. Add a small sideways toss once the simple version feels comfortable."
