Dannell Ellerbe has said that the New England Patriots will be vulnerable in 2013.
The Patriots lost leading wide receiver Wes Welker during free agency, while tight end Rob Gronkowski is an injury concern.
The Miami Dolphins linebacker told CBS Sports: "I think they are [vulnerable] but you have to prove it, you can't just talk about it.
"I was brought here to help knock them off. That doesn't mean we will, but we feel like we can. Like I said, we just have to prove it. You have to actually go do it."
The Dolphins have finished ahead of the Patriots just once since 2000.
