You're correct that NJ has become a very strong HS wrestling state, but I'm not sure where BC or Blair come into the picture. They don't have a starter on the team from either school, and most of their kids wrestled for their local public school; including Ashnault. If anything, the private schools are going to put negative pressure on Rutger's recruiting of elite in-state talent, because parents sending their kids to BC, Blair, Delbarton, etc are generally doing so specifically to either get their kids into an Ivy or to an elite wrestling school.
imo the real story in NJ is the proliferation of quality wrestling clubs, and the fact that the high-density of the state allows most kids to have multiple options for clubs. Apex, Iron Horse, Olympic, Scorpions; I know in North Jersey most kids have half a dozen quality clubs within 30 minutes of their home. I also think that putting all kids into a single group at states helps, because every single kid knows they have to be pretty damn elite if they want to place at states. When you have three of four state champions in your state, the pressure for kids to train hard 12 months out of the year isn't as high.
That said, I think the fact that Rutgers was able to qualify 10 guys for Nationals says something good about Rutgers, and also points out how amazing it is to Iowa fans that the Hawks aren't able to consistently field ten competitive wrestlers.
