AFL - Key Injuries - How much to line movement?

I don't think you will get much of an edge on this, lines don't usually come out until wednesday anyway and we usually know long before then if a star player will be out, if there is major doubt often the line on that game will not be released.  That being said, a star being out is generally not as big in an AFL game as it would be in basketball, also the result of a match rarely lands even close to the line so there isn't that much point hoping for a few points edge at another book, of course still worth looking for best lines but don't expect a great edge with your ideas.
