OK, I get that. But I suppose you're only able to 'rate them' in the sense of how strong their record was against their peers. It's impossible to rate their actual ability. And you get some wildly exaggerated stories...I guess we've all heard the story of the batsman (found it now, Albert Trott) who was purported to have hit a straight six over the Member's stand at Lord's in 1899.
