NBA Totals Historical Info Question

[sapidoc]

What is a good resource to use to figure out the following:

I want to know how often the total for an NBA basketball game falls within X points of the opening (or closing) line.

vegasinsider works for this, go to the scoreboard in the nba section and select the date you want to look at and what game. at the bottom of each scoreboard there is a link to the line movement. clicking on this brings up the line movement history for vegas casinos, so you can view each casinos opener, closer, and line movement throughout the day for each particular game.

hope this helps
