Indiana might not have seen the last of its one-class high school basketball tournament.
Bobby Cox, the commissioner of the state high school athletic association, who has been pressured by Indiana legislators, has scheduled 11 "town hall" meetings in April and May to gauge interest in returning to the one-class format, The Associated Press reported.
The Hoosier state scrapped the one-class tournament, which was romanticized in print, and the movie "Hoosiers," after the 1997 season.
Supporters of the multi-class system say it gives more schools opportunities to win state championships.
But those who want a return to one tournament for all schools say the multi-class format devalues the tournament and has depressed attendance.

Nobody connected with the East Detroit High School girls’ bowling team was singing the Blues this season.

Coach Cheryl DeFrance’s Shamrocks finished their best season in the seven-year history of the program by co-championing the MAC Blue Division with Dakota, each finishing with 11-1 records during the league season.
The Shamrocks also had success in tournament play winning once and finishing well in others.
East Detroit finished second at the regional meet in Taylor, and qualified for the team state meet in Battle Creek. Two bowlers, seniors Ashley Smith (second place) and Samantha Cisneros (10th place) also qualified for the individual state meet.
The Shamrocks performed very well at the state meet, too, but fell just short of the final round. They were in 10th place, and the top eight teams advanced.
Joining DeFrance on the coaching staff was assistant Kira DeFrance. The East Detroit bowlers were senior Catelin Campbell, senior Samantha Cisneros, sophomore Sarah Corbit, junior Haley Jugowicz, sophomore Alyssa Komlenovich, junior Kaitlyn Palmer and Ashley Smith, a senior.
