I've always liked Harper. He was, more often than not, a reliable understudy to Given. He always seemed to do a solid job whenever called upon.
Thought he was brilliant for us in the Championship as our number 1 - "safe hands" if you will. But unfortunately, with age, comes a decline in ability and that looks to have come Harper's way. But I do think that he still has the capabilities to be a decent backup for Krul (for one more season, at least).
It'll be a shame if he does leave, always thought he would retire here. If he does move on, then I wish him all the best. The man has my respect.
