The AFC East side, who beat the Cleveland Browns in their opening game of the season, travel to the Indianapolis Colts on Sunday.
The Dolphins head coach told reporters: "He's a very good football player. He played very well in his initial season in the National Football League.
"He's off to a good start again. He's an accurate passer. He can extend the play. He can scramble. He's very, very good. We're going to have our hands full.
"Again, I don't look at it in terms of comparing quarterbacks. As I've stated before, [Luck] is playing very well. He knows how to play the position. He knows the offense well, and he's playing at a high level."
Luck was the first pick in the 2012 Draft, leading the Colts to the playoffs in his rookie season.
