"Before this National Football League season started, the ESPN Stats & Information group introduced a new metric to measure effective quarterback play, something it called "Total Quarterback Rating" or Total QBR.

It considers this metric a more comprehensive measure of quarterback play than the passer rating system that has been used for years.

We have noticed that the Total QBR metric, as a football innovation, has not been as warmly and universally embraced as, say, the virtual first-down line in game telecasts. Perhaps it will at some point gain common use in football lexicon."
