What happened: A Nov. 10 trade returned Kirk Cousins to a former club. Quarterback starts have been an official statistic since 1950.
Why it matters: The move puts a new quarterback under center during a playoff push. It also gives Cousins little time to adjust to a different offense.
By the numbers: In 2026 through nine games, Cousins completed 202 of 315 passes for 2,340 yards, 20 touchdowns and eight interceptions.
What to watch: Sunday's opening snap would put the record on the books.
