I think we can comfortably get ourselves into the playoffs but 3rd place is going to need a serious run of form so, realistically, a bit out of reach this season.
If Carlisle carry on with the same points per game that they have done so far, they will end on 82 points. 3rd place in the last two seasons has been 85 points.
We've got 37 points, with 57 points left to play for, so getting 82 -85 points would need us to pick up 45-48 points out of 57 (W15 L4 / W16 L3
Never say never until it's mathematically impossible though, and hopefully a few teams around 3rd place will slip up along the way.
