"I just don't feel that team was as good as everybody was saying they were," Galette said of Miami. "We just abused the offensive line all game."
New Orleans' defense, worst in the league last season but resurgent under new coordinator Rob Ryan, also allowed fewer than 20 points for the fourth time in as many games.
Miami was driving for a potential go-ahead score in the second quarter when Tannehill tried to scramble up the middle and was stripped by linebacker Curtis Lofton. Safety Rafael Bush recovered on the New Orleans 38. That set up a drive that ended with Graham's leaping, juggling catch as three defenders converged on him.
Later in the half, Jabari Greer intercepted a pass intended for Brian Hartline and returned it 22 yards to the Miami 23. Several plays later, Sproles made a catch along the left sideline, spun away from a converging defender and scored his second touchdown with 55 seconds left in the half to make it 21-10.
Notes: Miami's 79 Monday night games are the most by any team. The Dolphins fell to 40-39 in those games. ... Payton has now coached in 100 regular season games, going 66-34 (71-37 including playoffs).
