The AFC East side have made 21 sacks, 10 interceptions and forced three fumbles so far this season.
Ahead of his side's game against the Bills on Sunday, the Miami Dolphins head coach told reporters: "They do an excellent job of takeaways. They are very multiple. They have good pressure package, a wide variety of what they do. They are playing well, a good defense.
"[Rookie linebacker Kiko Alonso has] been very, very productive. One of the things about a linebacker, you would like to see him make a lot of tackles. He hasn't missed very many tackles.
"He's obviously displayed a good awareness in pass defense and getting his hands on the ball and catching the ball. He's a good athlete. He's a good blitzer. He's off to a very good start."
The Bills are currently bottom of their division with a 2-4 record, while the 3-2 Dolphins sit second.
