This has been said before but this isn't just a MN problem. The % of top kids playing for their home school is very very low. Even 1 in 3 years.
Yes, this merits repeating. Rutgers isn't getting 5 stars from New Jersey, Penn State isn't getting 5 stars from PA (neither are Pitt or Temple), and Iowa hasn't gotten a 5 star from that state (yes, there actually have been two or three) since Ricky Davis in the late nineties. I don't know who would be the most recent five star from Wisconsin (probably Henry Ellenson) but Wisconsin didn't get him either.
This isn't just a Minnesota issue.
