Move over, Jason Campbell. With an eight-yard pass to Matt Jones late in the first half of Sunday’s 35-25 win over the Bills, Kirk Cousins became the new Redskins record-holder for completions in a season with 336 and counting.

Step aside, Mark Rypien, Jay Schroeder and Sonny Jurgensen. With his sixth 300-yard passing game of 2015, Cousins broke the franchise single-season record he previously shared with that trio.

Lest one think that Cousins’s record-setting numbers have come in garbage time of meaningless games, five of his six 300-yard performances have come since Week 7, and all five of those have been Redskins wins. Washington was 3-2 in the five games when Rypien and Schroeder eclipsed 300 yards passing in the 1989 and 1986 seasons, respectively. The Redskins were 0-2-3 when Jurgensen threw for at least 300 yards in 1967.

Cousins also continued his surprising pursuit of Robert Griffin III’s single-season record for rushing touchdowns by a Redskins QB (7) with his third in the last four weeks. Cousins’s five rushing touchdowns are more than Matt Jones and Alfred Morris combined and only two fewer than Panthers quarterback Cam Newton, who leads all quarterbacks in that category.

Cousins also joined Rypien, Trent Green and Norm Snead as the only Redskins quarterbacks since 1960 to throw for at least four touchdowns and run for at least one touchdown in a game. League-wide, that’s been done 36 times since 1960, including once by Jim Zorn in 1977. Newton has never done it.
