I am seeing this line at -4.5 now. It was 6 or even higher most of the week. This price indicates the book says on a neutral field SD is a 1.5 pt favorite? Is this similar to the GB/KC game when sharp money made the line just too easy on the squares (I only bet on a total in that game, but feel dumb for not taking GB -5). This line seems weird to me, but maybe I am missing something -- an injury?
