The purpose of this feature is to, effectively, "predict a prediction". The main feature of this site is the betting market power rankings, which are my attempt to reverse engineer what the betting market thinks about team and pitcher strength. What Todays' Games does is then take those rankings and try to predict how the betting market will set the moneylines and run totals for each day's games.
The goal here is to look for discrepancies between my prediction of the betting numbers and what they actually turned out to be. If my modeling perfectly captured how the betting market "thinks", then any discrepancy in the predictions would be due to new, late breaking information. During the NBA season, I found that these discrepancies were usually good indicators of key players either sitting out due to injury, or a key player returning from injury after a long absence.
