I started watching Argyle in 1995 so the typical names you’d expect from modern era are in my list. Couple of curveballs:
Rab Douglas in my GK list, as he contributed to one of my all time favourite Argyle matches / memories.
Bolasie as a winger. Unpredictable, exciting to see him run, and fair bloody play managing to go on and command a £29 million fee.
Number 1s:
McCormick
Billy
Wotton
Sinclair
Buzsaky
Littlejohn (again, 4-3 v. Torquay and his hat trick one of my favourite ever Argyle memories - bumped him up)
Sturrock
