Brock Purdy's 89.6 Total QBR is the highest by any quarterback through four games since 2020, when NFL MVP Aaron Rodgers had a 90.6 Total QBR. Purdy is the first QB with at least 10 touchdown passes and zero sacks taken in the first four games of a season since Dan Marino in 1984, the year he won NFL MVP.
