YouTube is packed with some brilliant trick shot/skill videos from all manner of sports, including American Football and Golf. However, there are few Rugby League ones of any worth.
This one, courtesy of RLWC2013, is, though. On it, you can watch Australian half-back Cooper Cronk kicking a ball out of his hands into a basketball hoop while in training for the World Cup.
Extremely skilful and entertaining, well worth a watch.
