I only have one book to compare and that is William Hill (Delaware) vs one offshore book for little players.... But I compared it over 3 different occasions. One for baseball season (Wold Series) NBA and College championships and late season NFL playoffs. In each of these 3 , the one offshore book had lines more favorable to the player. Is this true at most casinos or just William Hill? Or was it just the luck of the draw for 3 times?
