ABSTRACT: The
author examines the career passing statistics of Tom Brady (2000 to present), quarterback for
the New England Patriots of the National Football League (NFL). In the
categories of completions, attempts, completion percentage, passing yards,
yards per attempt, touchdowns, and interceptions, there is no evidence of
decline in per game averages since 2008 (when he tore his ACL) relative to his
seven seasons as a starter before 2008. Moreover, there is no evidence of any
statistically discernible performance change in his most recent four seasons as
a starter relative to the three prior seasons. His consistency based on the
coefficient of variation in games won is marginally better than his consistency
in games lost, with one notable exception. Tom Brady’s interceptions per game
were more consistent during losses than they were during wins.
