March Madness 101: An introduction to the NCAA basketball tournament

The NCAA Division 1 Men's Basketball Tournament, more commonly known as 'March Madness', begins next Tuesday in Dayton, Ohio, with the championship game taking place in New Orleans on April 2nd.

The month of March, beside its reputation as the gateway to spring, is also known for madness – “March” madness, that is. Beginning next Thursday, sixty-four men’s college basketball teams from the NCAA’s Division 1 will compete in this annual ritual that will have both devoted and novice college basketball fans scurrying to fill in their “brackets” to try and determine the winner of college basketball’s national title when the championship game is played in New Orleans on April 2. CBS will broadcast the tournament live throughout - both over the air and on

The bracket of teams is set with Sunday night’s selection show, and that promises to be infused with considerable emotion: from the height of elation for those borderline or “bubble” teams making the field, to the depths of disappointment of those having been “snubbed” or otherwise overlooked in the selection process. That process is handled by the NCAA Div. 1 men's basketball committee, made up of university athletic directors and conference commissioners. These so-called “at large” bids, thirty-seven in all, are based primarily on a team’s Ratings Percentage Index; in other words, the strength of its schedule and overall performance against that schedule.

Websites like compute these statistics, which are integral to compiling the teams’ overall rankings.  Typically, the lower a team’s RPI, the stronger its chances of receiving an at-large bid. Though RPI has been the generally accepted means of selecting teams for three decades, it is not infallible. Controversies can erupt when partisans of overlooked teams argue that their school’s statistics outweigh those of teams that were accepted. And with so much money and prestige at stake in making the tournament, the perceived subjectivity of the selection committee’s decisions can produce bitter and acrimonious debates.

However, RPI rankings are not the only means by which a team can enter the field. Thirty of the thirty-one remaining slots will be filled with conference champions. These come from both “major” conferences such as the Atlantic Coast Conference (ACC), Big East, Big Ten, etc., and “mid-major” conferences, or those that fall outside the traditional major or “power” conferences. Harvard University, in the tournament for the first time since 1946, is the only exception, as its conference, the Ivy League, does not have a championship tournament.

On the Tuesday and Wednesday immediately preceding the start of the round of 64, there will be a “First Four” playoff in Dayton, Ohio where eight teams (the lowest seeded at-large bids and the lowest seeded automatic bids) will play an elimination round. These games will be broadcast on truTV, beginning at 6:30 p.m. ET.

The four victorious teams then join the other sixty teams in the main tournament, which is divided into four geographic regions, East, West, Midwest and South – each consisting of sixteen seeded teams. The first seed always plays the sixteenth, the second the fifteenth, and so-on. Since the tournament went to sixty-four teams in 1984, a sixteen-seed has never beaten a first – though in 2001, fifteenth-seeded Hampton University defeated second-seed Iowa State. This is part of the appeal of the tournament – trying to correctly spot the “upsets” while simultaneously preserving your “Final Four” teams through to the championship round.

Additionally, it’s a great deal of fun to watch and check in on so many games in the first rounds – thirty-two games broadcast over the first Thursday and Friday that are frenetic, fast-paced and fraught with heartbreak and happiness. There are blowouts and “buzzer-beaters”, the drama of the occasional David-defeats-Goliath contest, tears of joy and sadness, the “pig piles” and court rushings – all concluding with one team’s jubilation in cutting down the nets following the championship game.

For nearly three weeks, this emotional roller coaster will keep college basketball fans riveted to the cathode-ray glow of our national campfire.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to
