Marian teams have no history of basketball success. St. Joe has a sporadic one, making the final 4 a few years before the ISHSAA(Indiana small high school athletic association) ruined that tournament. South bend public schools won't commit the resources and Penn and Mishawaka care far more about football and band.
Marian may have had its best year with him, but that's a low bar and far short of what Washington did with Skylar. Marian had nobody else who could keep opponent defenses honest.
