Here are the Power Rankings after round 20:
1. Melbourne Storm (Last week: 1)
The Storm continue to roll on and it looks like they've wrapped up another minor premiership. They're starting to work guys back - Ryan Papenhuyzen, Harry Grant - as they assemble their full-strength side. Melbourne have put new meaning to the word 'professional'.
2. Manly Sea Eagles (3)
I wrote last week that I was worried about Manly's defence - and I still am, because I don't feel like you can concede 24-odd points per game and be a genuine contender. When Des Hasler has taken teams to grand finals and won, they've been very good without the ball.
