This is accurate. Outside of Reimer (who is an incredible athlete, the exception to the rule), I can't say I've seen much development of other ILBs from Ruud.
His primary recruiting responsibility is Nebraska, particularly in fixing whatever problems we have in Omaha. I've heard it first hand from head coaches in the Omaha metro that he is terrible at that part of his job. Not present at the schools, hasn't built the relationships... that is their view of the world, and it has been consistent.
