Seven NFL teams remain undefeated entering Week 4. Two of them, the Miami Dolphins and New Orleans Saints, meet Monday Night in The Big Easy.

Oh, what might have been. Back in 2006, the Dolphins and Saints were the only teams seriously vying for the services of then-injured free agent Drew Brees. Miami opted for another quarterback coming back from surgery, Daunte Culpepper, and the rest is history.

Week 4 also marks the first of this season's two games in London and the beginning of bye weeks (the Green Bay Packers and Carolina Panthers are off).
