MATCHUP

No. 5 St.  John’s College (Washington, D.C.) at No. 9 Duncanville (Texas)

When: 9/14

Analysis: Could the winner of this game eventually become the Super 25 National Champion? Like the Mater Dei/St. Frances game on the same day, it’s not unthinkable. St. John’s has an incredibly difficult schedule, facing St. Joseph’s Prep, Duncanville, IMG and Mater Dei in a four-week stretch. Duncanville has the Texas gauntlet it is expected to face in the playoffs. If both teams go on successful runs, this game would make the difference.
