No. 3: Miami Dolphins

Analysis: This will surely upset Dolphins fans, many of whom feel their defense is elite. Well, as I've said before, Miami's defense is somewhat overrated. It's a good group and a tough group. But it's not elite. Miami was ranked No. 15 in total defense. Its pass defense was No. 25. The Dolphins are still looking for another pass-rusher opposite Cameron Wake, who had eight sacks in 2011. They also lost their leading tackler in Bell and their leader in Jason Taylor, who retired. Miami will play more 4-3 concepts under first-year defensive coordinator Kevin Coyle.
What a clown this Walker guy is. He says the Jets have the #1 defense and the Bills have the #2 defense. ESPN needs a new AFC East beat writer.
