a Des Movnes ues 4 J NEW BACKBOARD LOUIS A new basketball backboard curved convex- ly to make field goals pos- sible from the deep ends of the court was proposed Fri- day to increase the game’s scoring oppor- tunities. Coach For- rest C. (Phog) Allen of the University of Kansas (shown here with the board), who saw the con- vex board dem- onstrated, called it a “marvel ous idea” for in- creasing scor- ing and action —“that’s what puts over any sport.” A player in the new 4- foot extension zone finds it almost impos- sible to score with the pres- ent flat back- each side, elim- inates the “blind spots.” It was in- vented by two St. Louisans, Len Maune and George Cher- venko.
