It’s interesting to see where the pure win percentage approach diverges from the margin of victory approach that drives football-reference’s SRS. Top 5:
(1) BAL
(2) SFO
(3) DAL
(4) JAX
(5) BUF
The Eagles are down at 9 in SRS. The biggest differences are the Texans going from 8th in SRS to 19th in the colley matrix and Pittsburgh which jumps from 20th SRS to 10th. San Francisco jumps 9 spots up from 11th in colley to 2nd in SRS. Jets also move nine spots in the opposite direction (22nd SRS and 13th adjusted win%).
The correlation of the ordinal ranks is .81, so there’s still broad agreement between the two rankings but the disagreements are interesting.
