Indianapolis Colts head coach Chuck Pagano wary of Denver Broncos defense

Indianapolis Colts head coach Chuck Pagano has admitted that his side will face an extremely tough task to score on the defense of the Denver Broncos in their AFC divisional-round match.

The Broncos have the best statistical defense left in the conference, and although the Colts managed to score 24 points against John Fox's men earlier in the season, Pagano feels that his side will have to execute perfectly to register points.

Pagano told reporters: "Got a couple of enforcers at safety, got a ball hawk back there in Rahim Moore. He does a great job, got great range, gets a jump on the ball, anticipates well, has great ball skills. TJ Ward's a guy that comes down, plays in the box, covers tight ends, blitzes, does a lot of things.

"Linebackers are athletic. They run the ball extremely well. They're extremely well-coached. They're disciplined. Front to back, they don't give up very many big plays. You have to earn; they make you earn everything."

The Colts play the Broncos at Sports Authority Field for a place in the AFC championship game on Sunday.
