Villanova’s Game Five opponent also started the season with 1,000 points. But, their pre-season rating before their match-up against Villanova was 792. (i.e. Delaware is ranked lower than Villanova.) Before Game One, Delaware had a pre-season ranking of 620. In Games One-to-Three, Delaware beat Mt. St. Mary’s, NJIT, and Monmouth before playing Villanova. From these three wins, Delaware’s “pre-season ranking” relative to Villanova increased to from 620 to 792.
Every team starts the season with 1,000 points. After each game, these points increase and/or decrease based on whether the relevant team wins or loses and who they beat or lose to. Before the Game Six games, each team has a certain number of points. For Villanova, this number is 1,389. And, this 1,389 replaces the original 1,000 points that Villanova started with. Obviously, retroactively, the Games One through Games Five points will be changed by the 1,000 points being replaced by the 1,389 points (or whatever point total a team has pre-Game Six).
For Week Six and beyond, the points are the points.
