I'd like to have Jess in, just have a feeling he could be a good manager. However, given our history with past players in recent times it is probably better to stay away from any past players - including Jess, Strachan, Paatelainen or Black.
However just to contradict that, because I think he did play for us at one time, I think Jocky Scott would be the ideal person. He is experienced, will probably be his last big job, and probably the only one willing to take the job because he isn't worried about the knock-on impact to the rest of his career. Think he could bring the discipline and knowledge of the Scottish game to steady the ship - he really will be just to steady the ship though, not a long term replacement. Newell or Phil Brown could be decent shouts as well.
