interesting piece in today's WSJ regarding how to judge quarterback efficiency and play on more than just throwing alone
"That would take in the ability to move a team down the field," he said. "That would take in running ability." His argument, it turned out, foreshadowed a more intuitive formula devised by David Berri, a sports economist at the University of Southern Utah and the co-author of the book "The Wages of Wins."
Dr. Berri's system, which he called QB Score, analyzed data to determine which aspects of a game contributed most to a team's scoring or surrendering points. It places greater value on all the yards a quarterback gains (regardless of how he gains them) and on turnovers (including fumbles). A quarterback's rushing totals aren't a huge factor, Dr. Berri said, but they're taken into greater account.
