I don't know enough about the respective squads for this prediction to be serious but here goes:
Toronto Wolfpack: who am I to argue
Widnes: Retained a few decent-ish players, good youngsters (allegedly) so perhaps a bit of depth to their squad.
Toulouse: Despite Don Chorleyoni's enthusiasm they'll be close but no cigar
Halifax: Good for the play offs
Fev: Maybe nick fifth if they dual a few from Leeds who might want to shop-window a few they want off the cap.
Bradford: Good bit of progress on the cards
Leigh: consolidating, not sure whether they might sign more yet. If so, could go higher.
Batley: A scary female I know from there reads these boards so...
...I'll say they'll finish just above Dewsbury.
York: continue to grow, well clear of the drop.
Sheff: Not quite in the position of looking over their shoulders
Barrow: In the position of looking over their shoulders
Swinton: Phew!
Rochdale: Wearing the brown crown this year.
