MIAMI GARDENS, Fla. -- Pro Bowl defensive tackle Ndamukong Suh isn’t one to settle.

The Miami Dolphins' defense has been stout this preseason. The group has allowed just one field goal in nearly four quarters of work, and that field goal came as the result of a bad snap to Miami punter Matt Darr Saturday against the Atlanta Falcons that turned the ball over in Dolphins territory.

Miami’s starting defense stuffed Atlanta’s running game and sacked quarterback Matt Ryan three times in limited reps during Saturday’s 13-9 victory over the Falcons. With Suh, the Dolphins’ defensive line has been particularly impressive controlling the line of scrimmage and being disruptive. Miami sacked Ryan three times and held him to just 3 of 7 passing for 49 yards.

Still, Suh is not impressed.

“Honestly, there’s nothing I like just because consistency is going to be the key with us being a successful defense,” Suh said after Saturday’s game. “Any defense can have spurts and make big plays and do things of that nature. But if you can’t do it for a full four quarters and consistently do it game after game, it doesn’t mean anything because teams get better, they change every week.”

Miami’s big man isn't letting up. Suh, who signed a $114 million contract with the Dolphins this offseason, is trying to establish a culture of sustained excellence on defense, and three preseason games isn’t enough.

However, there is a lot to like about the Dolphins' defense thus far. Suh is playing at an elite level and with a high motor this preseason. He is commanding so much attention that Miami's other 10 defenders are thriving and also raising their level of play.

But Suh won't be satisfied unless Miami carries this momentum into the regular season. The Dolphins will travel to play the Washington Redskins in Week 1 on Sept. 13.

“We definitely need more polish, [but] it’s a good start,” said Suh, who helped lead the Detroit Lions to the NFL's No. 2 overall defense last season. “We’ve seen some positive things and there’s excitement here. We’re understanding how to play with each other, especially with the rush game and stopping the run is first and foremost. That’s what we pride our self on -- trying to hold the offense to as many negative yards as we can.”
