The list Westbrooks as a DL because he will play

both DE and DT in base. Mostly end when Donald gets back

The Rams scheme does not have 2 DEs it has 1 NT, one DT and one DE. They have chosen to list the NTs as DTs, so in terms of the nomenclature they have 2 DTs and one DE.

Longacre is a puzzle, though because in preseason I didn't see him at DE. I did see Fox at DE and OLB.

but just think 2 DTs, one DE and in this scheme on most plays one or the other of the OLBers is a DE.
