What about the bracket?

This is not a glib question. There are glib answers—use the side of the Empire State Building, paint it on Devils Tower, convert drive-in movie screens—but it’s a serious question. How do you make a bracket for a 346-team NCAA tournament?

The suggestion to expand the Big Dance to infinity and beyond came out of the Atlantic Coast Conference on Wednesday. The proposal: Every eligible Division I men’s team gets a bid in 2021, with the opening rounds taking the place of conference-championship tourneys and early-round bracketing based on geography. By the second week, the tourney would look pretty much like normal: 64 to 68 teams.
