I have been backtesting some stuff and was noticing huge differences in line moves from open to close. For instance this game took place on Jan 18 2007 and when I clicked on the odds history it shows like a 2 month jump in line movement. What is this? Here is the link. Any info would be great. Thanks in advance.
