SA FPG: Schedule-Adjusted Fantasy Points Per Game Allowed. Compares how many FP Player X scored against this defense vs. how many FPG Player X has averaged so far this year.
EX: If WR1's average 15 FPG vs. Stanford, but only 10 FPG throughout the year, then their SA FPG is 50% since Stanford allows 50% more FP compared to the Player's average.
