Extend his streak as the only active QB to throw 25+ TDs in five straight seasons
At the moment, no other signal-caller in the NFL has thrown at least 25 touchdown passes in five straight seasons. Not Aaron Rodgers, not Matt Ryan, not Matthew Stafford–nobody.
The closest active streak in this parameter belongs to Russell Wilson who has three straight years with 25 or more touchdown passes.
Kirk Cousins will likely extend his active streak and record his sixth straight such season in 2020 if he is not hampered by injury.
Four other quarterbacks in NFL history have fulfilled this particular feat more than five times including Peyton Manning (16 straight seasons), Drew Brees (11 straight), Philip Rivers (11 straight, and Tom Brady (10 straight).
Should this be considered a livable metric, Cousins is the next on the list. Aside from Manning, Brees, Rivers, and Brady, no other quarterback has ever thrown at least 25 touchdowns in a season for six straight years.
Considering the dozens of Hall of Fame signal-callers throughout the past century, this company is quite exclusive.
