We don't really play 433... I'm not really sure what we play anymore since Rodgers has gone off on some weird experiment to play every CB we have fit all at once.
The aim of our forward play is to be like a blob anyway, so there isn't really anyone who "plays down the middle" or who "plays out wide" when they play together, they just go where they like and I guess use their own nous and instinct to find space.
