This is the Bosa sack that jonny broke down from the trenches. What occurred downfield is worrisome and comforting at the same time.
Bucs attack with Switch Verticals. If you were with us last season, you'll recognize Switch Verticals as a route combination that the 49ers struggled with covering. It resulted in a number of chunk plays for the opposing offense as they used it to attack Cover3's sideline defender. Defending it takes communication and some pattern matching.
The idea is that yellow route occupies the sideline deep 1/3 defender so that red can attack the vacated area.
As Spoon sees a vertical route coming at him with another route behind it, he signals to Moore to take the first vertical. You can see Spoon's arm raised. At the same time, Dee Ford has destroyed the TE trying to pass block him.
The yellow WR knows he's going to be wide open. He's already run past Spoon, and Moore is totally flat footed. This is a blown coverage about to happen.
But the 49er's new 2019 pass rush covers for it an the blown coverage is never exploited. Only the guys in the meeting room know what's supposed to happen here, but my GUESS is that Moore covers the yellow route which allows Spoon to cover red. Thus accounting for both routes.
