Greg Cosell's Playoffs Preview: The Falcons will test Seahawks' D without Earl Thomas (Shutdown Corner)

Falcons coach Dan Quinn’s previous job was as the Seahawks defensive coordinator. As such, he runs a very similar defense to what the Seahawks use (a lot of “Cover 3” zone as a foundation, with three defensive backs each responsible for a deep third of the field), and the Seahawks understand how to beat it. In the first meeting, a 26-24 Seahawks win in Week 6, the Seahawks had one of the best game-plan approaches I’ve ever seen from them in regards to breaking down a defense with formation and pass game concepts.
