Philip Rivers announced his retirement Wednesday after an excellent season: 11-5 record, completed 68.0% of his passes for 4,169 yards with 24 touchdowns and 11 interceptions, 97.0 passer rating.
Was it the greatest last season by a quarterback?
The short answer is: No, it wasn't the greatest last season by a COLTS quarterback in the past three seasons. Andrew Luck threw for 4,593 yards with a 98.7 passer rating, both the best by a retiring quarterback. Rivers, however, was second in those two categories.
Another short answer? It isn't likely to be the best last season by a quarterback in 2020 if Drew Brees announces his retirement as expected.
