I’m not sure, but I thought i’d look up the worst teams not to be relegated in seasons when there was relegation, and who then made it to the start line the following year.
Paris ‘96, 7 points, 3 wins from 22 games.
Wakefield ‘02 12 points, 5 wins from 28.
Widnes ‘04 14 points, 7 wins from 28.
Wakefield ‘15 6 points, 3 wins from 23, 3 from 7 in middle 8s, won mpg.
We have 16 points already after 23 rounds. The highest number of points won by a bottom placed club in SL is Catalans’ 16 from 28 in their first season when they were exempted from relegation in 2006. Cas were relegated from second bottom that year with 19 points.
There have been a lot of SL teams a lot worse than the 2019 Rovers, just not in 2019.
