The problem with that play is that it's a chicken 💩 half-a$$ed call. Only 4 end up rushing, and Bosa of all people drops out into coverage to cover no one. And if a DE was spying Rattler, that's a stupid plan. If you're going to bother to show a blitz, actually blitz and bring more than 4. If Spags brings 7 guys to the LoS at the snap, at LEAST 5 are coming. I'd like to think that they are not blitzing out of these looks to get some tendencies on film that they can break later, but I have no way of knowing that.
Interesting bit of history that I don't think most people know. Spags and McDermott come from the same Jim Johnson/Eagles coaching tree and therefore have very similar philosophies. So when people insist that McDermott is a Tampa 2 guy, that is just flat out wrong. That was Leslie Frazier.
