And now there’s Ashburn, Va. The Post’s Matt Brooks reported this week that within a five-mile radius, at Stone Bridge, Broad Run and Briar Woods high schools, are three serious blue-chip quarterbacks. One, Stone Bridge junior Ryan Burns, already has a scholarship offer to Stanford and three other schools. Connor Jessop took Broad Run to the Division AA championship in 2009 after his brother Chris had done the same thing the year before. And Trace McSorley took Briar Woods to the AA state championship last year as a freshman.

“These are three really, really talented, really capable guys,” said Larry Kennan, who has worked with Burns and McSorley and is a former NFL offensive coordinator. “If you had three guys like them in the same state you’d feel good about it, and here they are in the same town. I’m blown away by it.”

All three also have cool quarterback-type names. “And at quarterback, from quarterback-rich Ashburn, Virginia ... Trace McSorley.”

As Loudoun’s population grows, its high school football programs are becoming powerhouses. Stone Bridge, Broad Run and Briar Woods have won four state titles in the past four years, and Stone Bridge has lost in the AAA title game the past two years.
