Sam Darnold and the New York Jets defense will have their hands full against a Buffalo Bills defense that loves Cover 3 and Cover 4.
Frazier, known for his safer Tampa 2 principles, is now running a Buffalo Bills defense influenced by McDermott. What’s surfaced is an ultra-soft unit (in terms of cushion) that looks to keep everything in front of it.
In 2019, the Bills defense gave up the fewest 20-plus and 40-plus-yard plays in the NFL. Playing Cover 4 (quarters) a good chunk of the time helps that cause, but it also allows vulnerabilities underneath.
Interestingly, Buffalo also does not blitz a ton. They finished 18th in rushing five or more players a year ago. But hey, who could argue with the results? Buffalo finished seventh in defensive DVOA, according to Football Outsiders.
Darnold will have to abide by certain keys this Sunday if he’s to lead his team to victory.
1. Downfield Patience Against Cover 4
This is the big one. Buffalo’s entire scheme is designed to wear out an offense. The unit never wants to allow a receiver behind it while keeping everything in front.
Part of how they accomplish this is by playing quarters coverage. They’ll show 4 presnap with plenty of room between the weapons on the defensive backs. Picking up four, five or six yards on first down will go a long way for Darnold.
The following example showcases Buffalo’s show 4 defense against the Houston Texans in the playoffs. Each DB has a No. 1 read and will react hard to a short break without much worry considering there will be another DB deep (most likely).
If Darnold could complete this play for five yards on first down, that will be the first key to cracking McDermott’s unit.
The following play is the first of the Week 17 game. Buffalo is in a Cover 4, and while Darnold does make the right decision (the flat to Jamison Crowder), he’s entirely too slow to get there:
