Maybe there is more to it than you are describing, but the picture you just painted makes it seem like a mess. In today's game, programs that recruit nationally (successfully) are extremely organized and put in structure and systems to allow them to maximize coverage and relationship within the limitations of the rules (well sometimes outside the limits as well but that is a different topic). Recruiting is more than just single self-contained cycles in which you are trying to land 25+/- kids a year - it is more of an ambassador program in which you are trying to develop long term relationships with high schools which might not have a prospect you are interested in each year.
Schools that do this successfully have a deep bullpen of support consisting of staffers the average fan has never heard of. They also do thing like employ a CRM (software) system and subscribe to "pro-grade" recruiting services (not talking Rivals, Scout, etc. but services/databases that compile info and charge way more for it than $10 a month). But at the end of the day the most important cog still is often the assistant coach who is able to go on the road and be the program's face.
What you described sounds more like it is ad hoc...almost hit and run...where you decide on a case by case basis of how you are going to recruit a kid. Sure, once an initial relationship with the recruit (not just the school) is established then it is smart to personalize it...including shifting the key contact to the guy's position coach. But what you described is not that (you made it seem like each position coach is out there all around the county looking just for kids at their position and calling in help when needed). The model I described is different (kind of the opposite). For example, Michigan just landed a DT and safety from Alabama. During interviews, post verbal, both credited our LB (their area recruiter and the first coach each mentioned) for getting them interested in the school and up for a visit...it was then that they started to build a relationship with their potential position coach, the DC and then HC. That example is not "each position coach being responsible for their position" but a team effort built on a structure that allows for more coverage. And what I described is not something that Harbaugh invented (by any means) but a pretty standard approach (to national recruiting) that has it's different variations (but still all similar) depending on school. Something in my gut tells me you guys do something similar and maybe what you described is an incomplete version of your practices?
Sorry. I thought you were one of ours, and as such, had a stronger background in the approach they are using.
