The Big Ten's strong March continued, with victories by Michigan and Illinois giving the conference two Final Four participants for the first time in 11 years. College basketball executives are set to decide on expanding March Madness to 76 teams next season and how these eight additional teams would be incorporated into the brackets. The cleanest move could be to create a 24-team opening round, with 12 games played before the main event begins Thursday. However, this could create a contentious decision about the type of teams assigned to the opening round. Big Ten commissioner Tony Petitti may push for a format that favors the richest leagues over mid- and low-majors. A decision on expansion must be made in April.
