Redskins quarterback Kirk Cousins took advantage of a matchup against the Saints’ struggling defense, throwing a career-high four touchdown passes — each one longer than any he had completed all season — as Washington routed New Orleans. Cousins was 20 for 25 passing for 324 yards, with no interceptions and a perfect passer rating of 158.3. His scoring throws came on passes of 78 yards, to running back Matt Jones; 16 and 8 yards, to tight end Jordan Reed; and 11 yards, to receiver Jamison Crowder. Cousins did not have a scoring toss of more than 7 yards this season.
