Every week, the first step of your DFS homework should be to examine the opening Vegas odds on all the NFL games for that week. Through some fairly simple algebra, it is easy to derive a spreadsheet that predicts team totals for every game, allowing you to develop a rudimentary game script to help narrow down your weekly decisions.
