Why this game is intriguing: Of course, we all knew the Cardinals would be 3-0 going into ... Nah, nevermind. No we didn't. The way that defense is playing, they will be in every game with a real chance to win. Inherently, this is a massive test for Dolphins rookie quarterback Ryan Tannehill. He may want to avoid budding star cornerback Patrick Peterson.
What to watch: An underrated storyline for the Cardinals involves quarterback John Skelton. The starter when the season began, his injury paved the way for Kevin Kolb's undefeated start. Now, Skelton is able to play ... but will he? As Arizona makes its case as a real contender, all eyes are STILL on the quarterbacks.
