Small prediction
1 Halifax
2 Barrow
3 Widnes
4 Featherstone
5 Toulouse
6 Whitehaven
I predict Halifax to be over 50 points, and Barrow to be 5 points above the rest. I expect the ranks 3 to 5 to be very close and one match could decide it either way.
Whitehaven follow without much chances to do better than 6 and Leigh will not be close from the 6th spot.
