I can't speak to the entire roster but I know for a fact Dennis Parker Jr. lives in the Jacobs Road area of Chesterfield, which is the opposite side of the city from John Marshall and not even in Richmond proper. Look up the difference in location of John Marshall High and Jacobs Road Elementary School on Google Maps. Parker currently has offers from LSU, NC State, Kansas, Ole Miss, Penn State, Rutgers, VCU, and Xavier.
Steve Stinson attended Trinity Episcopal prior to this season. Trinity is located near Midlothian and not remotely close to the John Marshall school district. Stinson currently has offers from Robert Morris, ETSU, Ohio, VT, and VCU.
Those are the two most difficult to hide based on their recruiting stature.
