These are the key biographies for development by WP:CRIC. All should have importance=high on their talk pages but the really important rating is the class one. We need all of these up to B-class at least and as many as possible up to GA and FA.
The biographies are those of people who are highly rated in reputable sources including those who appear in some of the Wisden, Hall of Fame and ICC Player of the Year listings such as Wisden Leading Cricketer in the World, Wisden Cricketers of the Century, Sir Garfield Sobers Trophy, Six Giants of the Wisden Century, Australian Cricket Hall of Fame, John Woodcock's Hundred Greatest of All Time and the ESPN Legends of Cricket list.
The list is not exhaustive so please add anyone we've missed but remember they have to be high importance by reference to reputable sources and not someone who hit a Twenty20 six last week.
