For these two particular guys, I think this is a simplistic view. Long's defenses have always been pretty good, and White is one of his mentors. Flip the script and put White as HC, I think having Rocky there calling plays would be something he wants. They'd work together on the gameplan all week, and White would be able to overrule anything.
Go find a DE that can make a bigger impact, and maybe Long looks better calling plays. The D still wasn't bad. Couple of rough games, but the entire team was a mess during some of them. It's a D that can do its part to win games if the offense can hold up its end of the bargain.
