An excellent point made by @hislopsoffsideagain on Twitter -
2014/15 - Dundee Utd finish 5th with 56 points. 2015/16 - Dundee Utd relegated with 31 points.
2014/15 - ICT finish 3rd with 65 points. 2016/17 - ICT relegated with 34 points.
2015/16 - Ross County finish 6th with 48 points. 2017/18 Ross County relegated with 29 points.
2016/17 - Partick Thistle finish 6th with 42 points. 2017/18 Partick Thistle relegated with 33 points.
Four teams relegated in the last four seasons, all of whom were in the top six a year or two previously. Two of those sides, us and County, won trophies in the two years before. Dundee Utd reached the league cup final the season before they were relegated, and the Scottish cup final the year before that.
Scottish teams are on a knife edge - lose even one or two good players or make a poor managerial appointment and you can drop like a stone very quickly.
