Legend is over used, a club can only have so many legends, status which is earned over years and games. i'd say most of the current team haven't done enough to be considered legends maybe with the exception of Turnbull due to his long-ish service and 2 promotions - though it never felt like he was an integral part of either or a top player in those teams so im not sure he qualifies in my eyes.
Fair to say, Jim is probably the only one I would consider an SCFC legend personally though the whole squad from last year deserve to be fondly remembered even if they end up at Fylde or FCUM!
