Our ranking system is based on Google's PageRank algorithm.It is explained in some detail in past posts. A directed graph is created to represent the current years season. Each team is represented by a node in the graph. For every game played a directed edge is created from the loser pointing to the winner and it is weighted by the Margin of Victory.
In the Pagerank model each link from a webpage i to webpage j causes webpage i to give some of its own Pagerank to webpage j. This is often characterized as webpage i voting for webpage j. In our system the losing team essentially votes for the winning team with a number of votes equal to the margin of victory. Last week the Falcons beat the Redskins 24 to 17, in the graph a directed edge from the Redskins to the Falcons with a weight of 7 was created.
The season graph so far can be visualized in the following graph.
The numerical rankings are as follows:
