The NRL can be split into tiers after five rounds: the "power three", the middle and the bottom.
Some performances on the weekend were reflective of this difference in class. Depth is very important if you want to win a competition, so the sides who have injuries in key positions might struggle for a little while - and that could see more scorelines blow out.
1. Penrith Panthers (Last week: 1)
The Panthers have spent a long, long time at number one over the past two seasons. Just professional against the Raiders. They got punched in the face early, and some teams cower after that, but Penrith took the challenge head-on to score points and build pressure.
