Notre Dame has shown that they can recruit offensive linemen and tight ends very well - just look at current NFL rosters. They have also been able to recruit good even if not great running backs. What they have had trouble recruiting is elite wide receivers with speed.
So given those facts, it makes perfect sense for Rees to use a power-running and tight-end heavy scheme. It makes little sense to put together a wide open passing attack with multiple wide outs. He doesn't have the personnel for that. Let ND manage to recruit multiple wide outs with speed (and be able to develop them so that they can get on the field, you then would see a more pass heavy offensive scheme from Rees.
