The Cowboys head coach told reporters: "I just think he's an impressive player. Quarterback is a hard position to play, and to step in as a rookie like he did last year and play as much as he did and as well as he did was impressive.
"I think he's just continued his growth. It's a different offensive scheme, but you can tell he's a pretty darn good football player.
"He understands what they're trying to get accomplished there. He can stand in the pocket and make a lot of big throws for them. He's played very efficiently."
Foles has 542 passing yards and six touchdown passes so far this season.
