what exactly is that style of defense?
a mix of deep cover 2 and cover 2 man - no blitzing, dropping 7 and forcing them to dink their way downfield - potentially using layered/delayed rushes upfront to stop Mahomes escaping
chargers ran mostly cover 2 man (but tbf they do that more than anyone in the league and it's a staple of staley's defence) - bills tonight look like they ran a ton of cover 2 zone but hard to say for sure without the all-22 and the ravens mixed it up a bit more with some different kinds of coverages and hiding the cover 2 a bit more (had the advantage that we ran that defence without anyone expecting it of us) and introduced the layered rushes and stuff on top of that too
basically philosophically you leave your guys up front to deal with the running game and dare them to dink and dunk you - and try and get pressure with 4
it definitely helps that the chargers have bosa and others
the bills have jerry hughes and just drafted rousseau and basham after drafting epenesa the year before
the ravens have houston and campbell and just drafted oweh
