"Beginning next season, both the Big Ten Men’s and Women’s Basketball Tournament fields will expand to 15 teams (from 14), a format that maintains the five-day schedule of the event, provides access to all teams in contention for postseason invitations, and will maintain a double bye for each of the top four seeds while seeds 5-9 will receive a single bye.Big Ten Conference Announces Future Basketball Scheduling Formats

Both the men’s and women’s conference schedules will remain at 20 and 18 contests, respectively, for each school.
