Well if we had a back 4 that'd take care of itself.
With the back 5, if Rawlo moves over, that'd leave Chicksen bang in the middle (have we ever seen that?)...he won't move to LB/LWB coz DKE is standing there (hasn't been in their half according to commentary). If we had a real LWB, Chicksen could play behind him. It's a mess.
