A handball is more than just hitting a target by executing a skill well. There's a creative element to handballing, only the best have the skills but also the tactical genius to turn a handpass into a work of art.
Best I've seen was Maurice Rioli Snr, closely followed by Sheds. Ian Stewart & Dale Weightman deserve mentions here too.
Both Maurice & Sheds had the vision to spot an opening, the decision making & composure to time their release perfectly & the skill to deliver the ball well, consistently putting team mates into space. That is what makes an elite handballer. Hitting a target is very nice, but changing the way the game is played is next level stuff.
