Here’s what to know about Selection Sunday

March Madness is almost upon us.

The 68-team fields for both the men’s and women’s NCAA Division I college basketball tournaments will be unveiled on Sunday, March 16.

Around half of the tournament berths are automatically locked in when teams win their conference tournaments. Those tournaments will continue over the next few days, with teams on the bubble trying to pick up enough wins to shine up their resumes, while smaller schools desperate for their only shot to dance.

That will all be wrapped up by Sunday afternoon — leaving just the brackets to be revealed in selection shows that evening.

When will the brackets be released? 

The men’s bracket will be released during a selection show that begins at 6 p.m. Eastern time on CBS. The women’s bracket will have its own selection show at 8 p.m. Eastern time on ESPN.

Who are expected to be the top seeds? 

In the men’s bracket, schools in the South have dominated this season. The top seeds are expected to include Auburn, who’ve reached the Final Four only once in school history. Two other SEC schools, Florida and Alabama, are also in the mix for No. 1 seeds. The conference hasn’t won a basketball title since Kentucky in 2012 — and only two other SEC schools have ever won a title.

The perennial contender Duke is also likely to be back in a top slot. But a major concern for them arose Thursday when star freshman Cooper Flagg sprained his ankle and had to be rolled to the locker room in a wheelchair.

South Carolina and head coach Dawn Staley seem to be a lock for another No. 1 seed. Look for stars JuJu Watkins and Paige Bueckers to lead USC and UConn, respectively, to other high seeds.

Who could be this year’s Cinderella teams? 

Top seeds have always had more success in the women’s tournament, where the disparity between the haves and have nots is much wider than in the men’s game. Put another way, no team worse than a No. 3 seed has ever cut down the nets.

One contender to make that history could be Iowa. Yes, the Hawkeyes have been runner-ups the last two years in a row. But that was with megastar Caitlin Clark, who graduated last year and left for the WNBA. This year, Iowa doesn’t have the resume for a higher seed, but still the Hawkeyes have been frisky, knocking off then-No. 4 USC in February on the day Clark’s jersey was retired.
