What the linesmakers do is, they give you a free pt or two if they want action on one team more than they already have, they did that with houston i got them at +10, they did that with washington and im laying off....youll see this from time to time if you wait till the last minute of games, same reason they just did it with portland they moved the line from 4/ 3 1/2 on port to +2 because everyone was loading up on portland.
