In a recent interview about his appointment to the Recruiting Coordinator position, Chuck Martin outlined the 6 filters that players must make it through to be recruited by Notre Dame. These 6 filters create a funnel that narrows down the pol of talent considerably for ND. Lots of kids qualify for the first level of the funnel - athletic profile - any 3, 4 or 5-star kid fits it for his respective position probably. It means he's a known quantity, he's rated, etc. Here's the rest of BK's RKG Funnel:

For many programs, the funnel pretty much ends after Athletic Profile. Besides a minimum test score, most don't care about academics. Besides blatant arrests on the record, most don't care about background, family life, social life, character. Heck, some (see: Florida) prefer it.
The funnel ND uses is something that BK has worked with for a while - pre-ND - and it fits ND to a tee.
I like it.
But it got me wondering what kind of funnels other coaches use. So I did some snooping, snuck into a few offices, and found the secret funnels for UF, USC and Michigan (which sucks).
Florida Coaching Staff's Funnel

This is pretty obvious once you see it, but it's worth posting anyway. You know that Urban has a poster up on his wall and he just stares at it....AK-47? Check.
USC (Poodle AND Kiffin era) Coaching Staff's Funnel

For the USC Staff, it's much more about the Benjamins and the glitz and glamor of LA, and a lot less about blatant lying to recruits. But the funnel still works.
Michigan Coaching Staff's Funnel
RR HAS to have one of these as well. Because, I mean, you have to make sure the kid's okay with working out from 7am to 4am, right?

*Michigan's horrible African-American grad rate is well-documented. Here, and everywhere.
