Drew Brees passed for 413 yards and four touchdowns, and the Saints turned a clash of unbeaten teams into a lopsided affair, beating the Miami Dolphins 38-17 on Monday night.
Two of Brees' touchdowns went to Jimmy Graham for 27 and 43 yards as the tight end had at least 100 yards receiving for the third straight game.
Brees' other scoring strikes went to Benjamin Watson and Darren Sproles who also rushed for a touchdown.
Sproles' 5-yard scoring run on the game's opening series gave the Saints a lead they would not relinquish en route to their first 4-0 start since their Super Bowl championship season of 2009
Ryan Tannehill passed for 249 yards and a touchdown to Charles Clay but his four turnovers on a fumble and three interceptions hurt Miami (3-1).
