I have to add my vote for the Kellaways, Duncan first, though, closely followed by Andy. I remember one game years ago when Dunc was standing Carey and doing a really good job of it, and then was asked to go into the midfield and take (I think) Stevens. Again, did another blanket job. As for courage, he either didn't know what fear was or knew about it and simply didn't rate personal safety at all.
Would have loved to have seen Captain Blood in full flight.
Maurice Rioli used to cop it regularly as well (physically and verbally in the days before racism was rightly stamped out of football) and just kept getting up and going to find the footy.
From other clubs - Brereton, Carey, Archer, Hayes, Harvey, Ablett snr, Dipper.
One from left field, unpire Glenn James. To put up with the *smile* he used to cop from supporters (and some players) every week, sometimes even off the field, just shows what a class bloke he is.
