March Madness is here. Bracket reveal is the first step in a likely NCAA Tournament free-for-all

The story of March Madness figures to look a lot like the story of the regular season that led up to it: a healthy cross-section of very good teams, few dominant ones and no strong consensus on who's the best bet to be cutting down nets at the Final Four in Arizona.

The story of March Madness figures to look a lot like the story of the regular season that led up to it: a healthy cross-section of very good teams, few dominant ones and no strong consensus on who's the best bet to be cutting down nets at the Final Four in Arizona.

Defending champion Connecticut is a slight favorite to repeat, according to FanDuel Sportsbook, followed by Houston and Purdue. Barring something unexpected, all three teams will earn No. 1 seeds when the brackets come out Sunday evening. Tennessee and North Carolina are in the mix for the fourth top spot, along with Arizona and maybe even Iowa State, which on Saturday crushed Houston 69-41 in the Big 12 Tournament championship.

The NCAA Tournament begins Tuesday with the First Four, followed by 32 first-round games on Thursday and Friday. The Final Four is set for Glendale, Arizona, on April 6-8.

As always, the more interesting discussions will be about the ever-shrinking bubble and who will be among the last to squeak into the field of 68 teams — 32 of which qualify automatically by winning their postseason conference tournaments.

A handful of unexpected results in conference tournaments — among them, North Carolina State winning the Atlantic Coast, Florida Atlantic losing in the American Athletic and Oregon winning the Pac-12 — meant highly rated teams would gobble up more of the remaining 34 at-large spots. It made the wait more perilous for teams such as Indiana State, Virginia, Seton Hall and St. John's, while turning Sunday into a much more difficult journey for the committee that picks the brackets.

“This is my fifth year doing this — never have enjoyed Sat night because of how hard it is to select the final teams,” Jamie Pollard, the athletic director at Iowa State who is on the committee, said on social media. “This year is harder than all my previous years combined. Just gut wrenching knowing some very good teams will unfortunately not be dancing.”

Several weeks ago, Gonzaga was considered a bubble team, but a stretch of nine wins in 10 games elevated the Zags, and though they lost their conference tournament final to Saint Mary’s, they will make the field for the 25th consecutive year. That would be one fewer than Michigan State, which is trying to reach its nation-leading 26th straight tournament — if it makes it in off the bubble.
