 The selection committee's work to seed the teams is just as vital as their work to select the at-large teams.While the selection process starts before the seeding process, the two often overlap.Some conference tournaments do not finish until Selection Sunday itself, and there is only one hour between the end of the last game (usually the Big Ten Tournament championship game) and when the brackets are officially unveiled, so the committee cannot wait until after all the games are played to start determining the seeds.
