Five games in, the 49ers defense is 3rd in EPA per play, 4th in scoring, and off to the 7th-best DVOA start in history. And the true starting defense has never played a snap together.

Raheem Morris is winning with simulated pressures and a young secondary while the four-man rush heals. When Bosa and Mykel Williams share the field, he can win rushing four too. That toggle is how you end up with a McDonalds Defense of your own.
