Neither of these two would have been my top choice but if I had to pick it would be Denbrock, simply for the fact that he's been an OC at the highest level of competition (SEC) and is at least partly responsible for developing Daniels who is a consensus top 5 pick right now.
More importantly though, ND needs to start hiring coaching staff that are better on the recruiting trail. Tireless motivated recruiters (we need more of them on our staff). Finding recruiters during coaching hires has NEVER seem to be a focus of the university though for some reason and it doesn't make a lot of sense when the biggest impediment to notre dame's national championship aspirations is lack of upside/elite talent.
