I think it is extremely unlikely someone would be able to get away with address buying in a town the size of Rochester. The football program is under such intense scrutiny (both from within the school district and outside), rumors would spread, word would get out, and other schools would file complaints.
Simply put, Rochester and DL do not recruit in the sense of poaching athletes. Yes, talent shows up every now and then...but they have to move into the school district. I know where the Cox brothers lived, where Matt Wike lived, where Adam Conrady lived, and I know where Jack Swaney currently lives. Not because I'm a stalker...it's a small town...everyone knows where everyone lives. And again...there are less than 10 impactful players that have moved into RSD to play since 2010. If DL was recruiting, that's not a very successful resume!
If someone's definition of recruiting is "talking to a kid", or "convincing a kid to play", then every public school coach recruits.
The accusations about recruiting exist, I think, because to many it is unimaginable that DL can continue to turn out this level of success year in and year out without recruiting. But he does...he's a phenomenal coach with a phenomenal staff. That coaching is carried all the way down the grades...down to 2nd grade JFL.
