I know this is everyone's "opinion" but some of the names being put forward shouldn't even be mentioned in the same breath as "Team of the Century" (notably some more recent posts).
To qualify to be discussed you would need to be have hit the record books at the very least, mail medallist (multiple), multiple premiership player, leading goal kicker etc. To mention blokes who do not tick any of those blokes is laughable
Before you get on your horses and say "so if our club hasn't been successful it means the player does not qualify", well in this instance unless your player was heads/shoulders and whatever else you can find above the rest of the team then maybe they could be considered, taking into consideration what would've that player been like in a premiership team amongst other outstanding players, most likely not as big a standout, there may be an odd exception.
Defenders will be the harder one's, unlikely to have too many mail medallists but certainly some dour and perhaps high games tallies along with premierships might be looked at?
Unfortunately most posters aside from BTP and a few others know anything/very little prior to the 90's so doesn't really get too much air time but this should be the criteria for discussing/picking the "Team of the Century", 21 players from 100 years from around 20 clubs that have participated in the SFL.
