Neilson coached the worst passing Defense in the NFL last season. Anyway, position coaches (and "senior assistants") don't make the defensive backfield better. They need starter upgrades all around--currently they have one legit starting level DB on the roster at this point. Is the guy from NE bringing Christian Gonzalez with him?
It seems an annual event: each year end (playoff loss) presser, McBeane tells us what they're going to do differently next year...and fire a coordinator.
