Defensive statistics and point modifiers:

Each sack = 1 point
Each interception = 2 points
Each fumble recovery = 2 points
Each TD = 6 points
Each safety = 2 points
Each blocked kick = 2 points
Shutout = 10 points
1-6 points allowed = 7 points
7-13 points allowed = 4 points
14-20 points allowed = 1 point
21-27 points allowed = 0 points
28-34 points allowed = -1 points
35+ points allowed = -4 points

计算防守得分时看你选的队在比赛中各项统计的得分总和。周六是Tennessee vs Miami,
周日NYG vs PHI,你们老大深谙此道，TN首发是个不错的选择。
