Ratings are designed to rank teams based on their results in the current season. This is a bit different than determining if team X will beat team Y (although the higher rated team would generally be expected to win) and who will make the NCAA tournament (bracketology is a bit more nuanced).
What is NOT factored inPredictions incorporate team ratings as well as prior head-to-head matchups, home court advantage, and prior season ratings. Certain factors that betting lines may include such as injuries, roster changes, and other unusual circumstances are not factored into our predictions.
