The Chargers are 5-1 and lead Manning’s Broncos in the AFC West, and Rivers probably has been the league’s best and most consistent performer so far.
He has completed 69.3 percent of his passes. He has 15 touchdown passes and only two interceptions. He has an NFL-best passer rating of 117.6. Rivers’s passer rating has been above 120 in five straight games, a first in league history. His worst single-game passer rating during the five-game stretch of brilliance is the 123.8 that he posted in last Sunday’s victory over the Oakland Raiders in which he threw for 313 yards, with three touchdowns and no interceptions.
