With eight rounds to play, Rhinos winger Ash Handley is the competition's top metre-maker, according to official Super League stats complied by Opta.
Handley, who is also Super League's third-highest try scorer, has had an outstanding campaign for Leeds, in tough circumstances.
He is one of two Leeds players in the leading 20, but Castleford Tigers beat that with three.
Here's how Super League's top 20 metre-makers look ahead of round 20.
