Say a line moves from -9 to -10 for a nba or ncaab game. If I could still get the -9 at -110 is that value regardless of other stats or reasoning? I've often heard that if you know which way the line was going to move you could be very profitable. This is basically the same thing, you know the line is going to move because it already has. Therefore it would seem profitable if you could still get the -9 in this situation at -110 odds. Just thinking, give me your insights please.
