In the NFL the longer you're around the more film history you generate for offenses to pick you apart. Dom was an innovator but injuries and youth (and maybe his own loss of energy/interest) limits what he can do that's new. I've always suspected that Dom's defenses are too complicated. Too many moving parts. If you're guys are vets and healthy, no problem. But if not, you've got trouble. Maybe a youthful innovator like Dave Aranda is what we need.
