To answer the original question, I don't go to see HCAFC any more but I try to follow them each week. I'd say they have as good a chance as any of the other teams you mention of staying up and may even surprise a few people on the way. I think they have a good manager and at the moment have a good team spirit. I am always a fairly confident sports supporter and I'd bet they would stay up.
Not too sure on how Graham will perform for them, but Koren and Aluko will be the star players. If you were to pick any of those for your fantasy team you may want to pick Aluko as a cheap striker or Koren as a cheap midifielder. Koren is great at free kicks and may take the penalties and whilst Aluko is an unproven EPL striker, he was fantastic for us last season (when not injured).
As for defenders, Figeuroa and Chester will be the stand out players in that lineup, particularly Chester, whom we have been lucky to keep hold of.
