QBR ranks: Alex Smith keeps winning


The San Francisco 49ers have won with Alex Smith playing at an elite level.

They have won with him playing very well (Sunday against Cleveland, and against Seattle in the opener). They have won with Smith playing below average (at Cincinnati and at Philadelphia, save for a tremendous third quarter against the Eagles).

They have won with him playing poorly (at Detroit, save for the final minutes).

That's a lot of winning for a quarterback with a 19-31 starting record before this season.

Smith is the only quarterback in the NFC West to post a single-game Total QBR score of 70 or higher (50 being average, 100 being maximum). Smith has done it three times, as the first chart below shows. The 49ers have supported him well enough to win three of the four games when Smith's QBR ranged from 10.3 to 47.5.
