OK, just to prove I am not crazy, I am going to submit this again. And, this time, with documentation.
My opponent ran this against me five times in my most recent game. The play is PA TE Drag out of the goal line set. It includes three RB and two TE. But, when I am trying to put together my defensive rules, there is no 320 option in the dropdown menu.
it's just the 2rb3te formation. for some reason the player card always lists the third te as a fb. Pretty much every playbook has that PA TE drag, you can see it if you just look through your own playbook and check the 2RB3TE formation.
