2015: Week 15

Five games. Every ranked team that played won. Winners are listed first; numbers before names are AP ranks going in.

Big days

Ranked by a points score for each kind of game (yards, touchdowns, tackles, sacks).
How we rankRanked by yards plus 20 for each touchdown (passing: less 20 for each interception); defense (from 2016, when the box scores carry tackles) by points: 8 a tackle, 12 a tackle for loss, 30 a sack (a sack is also a tackle for loss, so 42 in all), 40 an interception, 60 a touchdown.
