There's Tom Brady for quarterbacks. Von Miller for edge rushers. The Broncos' Aqib Talib and Chris Harris for cornerbacks. The Cowboys for offensive lines. Every position has players or units that are almost unanimously considered the best at what they do.

For Malcolm Jenkins and Rodney McLeod - and let's face it, every other safety tandem out there - there are Earl Thomas and Kam Chancellor. The Eagles safeties said earlier this season that they wanted to be mentioned in the same breath as the Seahawks safeties.
