All this depends on how long people have been supporting Argyle !
There were apparently great teams in the 1930s and 1950s which I never saw play. Nor did I see the teams of the 1970s featuring Mariner etc. And how good was the likes of Fred Craig from the 1920s? - I won't ever know.
As someone who has been watching since the 1980s players who really stood out would include the following... Tynan, Dalton, Castle, McCall, Morrison, Marker, Poole, Mark Smith, Mark Stuart, Nalis, Norris, Marshall, Friio. Maybe Carey. As a target man, Evans was the best I saw. The best loan must be Scott Sinclair who was electric.
Its also worth remembering that the best Argyle teams have played at 2nd tier (Championship) level so its hard to make comparisons with the current team at 4th tier level.
I think its fair to say that professional standards and physical fitness have improved over the years. You couldn't go out and have a few pints after training like Tynan did. But on the other hand, these players were the best of their era and would have probably played just as well in the modern era of football.
