If they did a couple of Covid-swerves re Catalans, Hull KR and Saints, they could go after us and Huddersfield and get 3 wins out of 19. If we played our remaining games and lost them all, we'd have 5 wins out of 22. That would still put us above them,
Just swerve Catalans and Saints and beat us, Huddersfield and Hull KR, it would be 4 wins out of 20. 20%. That would still be good enough for us.
They only way they can stay up is by winning 4 more games but play one less game, because of points difference.
