LANDOVER - Kirk Cousins threw for a career-high four touchdowns - each one longer than any scoring pass he'd completed all season - to lead the Washington Redskins past the New Orleans Saints 47-14 on Sunday.

Cousins went 20 for 25 for 324 yards, zero interceptions and a perfect passer rating of 158.3, connecting for TDs of 78 yards to Matt Jones, 16 and 8 yards to Jordan Reed, and 11 yards to Jamison Crowder.

Cousins didn't have a touchdown toss of more than 7 yards until he got to go up against the Saints' porous and poor-tackling defense.

The 33-point margin of victory for the Redskins (4-5) was the team's largest since beating San Francisco by 35, 52-17, in October 2005.

The Saints (4-6) lost their second game in a row, following a run of three victories that briefly got them to .500.
