If there was a conspiracy in place for SK to give up a 1 year salary pay out to join Thistle on a, no doubt, lesser wage, then it sounds like a plan cooked up by Pinky and the Brain.
Putting the "abuse by fans" excuse aside for a moment, it felt like SK was running out of ideas for us and that was turning into frustration with everyone from the refs and the media to VAR and, of course, the fans.
I don't think he was lined up for the sack, but the resignation didn't surprise me too much. He hadn't gone full "deer in the headlights" in his interviews, but he was heading in that direction.
He was never going to be out the game for very long because that's just how football works. Whether it's at Thistle, Ross County, or some other club, it's odds on he'll have a new job by the spring.
