A Few Yards Short of Intelligible

Whoever invented the NFL's quarterback passing rating statistic must be related to the guy who created the English system of measurement.

Slate.com:

The NFL's system uses four metrics: completion percentage, yards per attempt, percentage of touchdowns thrown per attempt, and percentage of interceptions per attempt. The four factors are weighted equally.

A score between zero and 2.375 is calculated for each metric. A score of 1.0 is supposed to be average. A completely average quarterback would complete 50 percent of his passes, average 7 yards per attempt, throw 5 percent of his passes for touchdowns, and throw an interception 5.5 percent of the time.

Uh...what...?

Oh, hey, look, a baseball game is on!
