A metric which represents a team's average schedule difficulty faced by each team in the games that it's played so far. The schedule difficulty of a given game takes into account the rating of the opponent and the location of the game. Strength of schedule can be calculated by compiling the win/ loss records and the current power ratings of the team's opponents. The greater the SOS number, the more difficult a schedule that team has.

Strength Of Schedule (SOS) Formula= (2/3)* (Opponents' Average Winning Percentage)+ (1/3)*(Opponents' Opponents' Average Winning Percentage)
