To win in the modern NFL, you need to stop the pass. There are a number of ways to achieve this, but two very distinct philosophical approaches.
On one side of the coin, there are coaches like the Cowboys’ Rod Marinelli, who advocates for a strong four-man rush with coverage behind it. The offense may know what’s coming, but the idea is that if players know their responsibilities backwards, it will allow them to play at 100 mph.
The other side of the coin includes coaches like the Raiders’ defensive coordinator Paul Guenther.
