Saint John Vianney's Madison St. Rose (Peter Ackerman / USA TODAY NETWORK)

The Saint John Vianney (N.J.) Lancers have had a brilliant season, most recently defeating Rutgers Prep in an 87-48 rout. The team is a level above the rest in New Jersey, but it also has bigger goals.

Saint John Vianney, slotted No. 5 in this week’s JWS high school rankings, will have a legitimate claim for the nation’s top-ranked team if it can defeat No. 1 Sidwell Friends on Sunday in a neutral site game in Delaware.

It won’t come easy, however. The Quakers are a juggernaut and have rarely been tested this season. Whatever happens, the national basketball landscape won’t look the same a week from now. Even this week, there was plenty of reshuffling from last week’s rankings.
