Over the next few weeks, Zero Tackle will be taking a look at the best rugby league players from every age group as fans across the country eagerly await the NRL's return.

While an Under-18s Australian Schoolboys team is named annually, Zero Tackle will be naming the best players from each age group who are set to be watched closely in the near future or have already proven themselves as stars of the 13-man code.

Headlined by the duo of Ethan Strange and Isaiya Katoa, the Under-21s age bracket includes multiple representative stars and others who are just slowly starting their rugby league career.

This includes South Sydney Rabbitohs utility Jye Gray, New Zealand Kiwis fullback Keano Kini, Queensland Maroons centre Robert Toia and premiership-winning winger Paul Alamoti from the Penrith Panthers.
