In 1983 the club decided to acknowledge the achievements of those players it felt had improved their performances most significantly over the course of the previous season, with the introduction of the Most Improved Player award.
As far as we can tell, this had only been presented once before, to Graeme Jenkin for his efforts in the 1970 season.
For most of its life the award was named after club benefactor Joseph Wren, the son of legendary club figure John Wren. From 2000 the Most Improved Player award ceased and the Joseph Wren Memorial Trophy was instead given to the best player in the reserves team.
