We can't maintain too many players on the bench though, so having some flex is useful.
Dragusin can come in and VDV can offer an option at LB. It might make us more solid defensively for certain games too. What Davies lacks in technical ability and size, he makes up for in experience and anticipation. A bit like Royal, he can be super sharp defending and move and react quicker that larger defenders. He knows the system, gives his all etc.
If we sign another LB, we'd need to shift at least Davies, and I don't see it.
