We have to score 4 more points in 5 games than one of the three sides on 26 points, and at least a point more than Leigh at the same time. Our points difference isn't great so we might even have to score more points than that. To have a shot we'll probably have to win at least four games as the worst of the teams 4 points ahead of us would only need to win 2 in the same time. If we don't win by much we'd likely have to win all five games to sneak in.
Of our remaining games we should beat Cats, London and Hull. We then play Wigan and KR, both away from home at a point when they'll be gearing up for play offs - the League Leadership might still be up for grabs for one or both as well.
The fact is that even though we're playing better under Arthur we've won 2 and lost 3. We look a better coached side but the fundamental problems of an undersized pack and lack of points still remain. Its not mathematically impossible yet, but it might be by the time we get to the last two games, even if we win the three beforehand.
