March Madness: What it is & How it Works (Full Guide)

Our college basketball expert @SidekicksPicks breaks down everything March Madness so you can go into the tournament armed with all the information you need to bet with confidence.

He breaks down how teams get selected, the tournament format, the most successful teams/conferences and key betting trends.

What is March Madness?

March Madness, for a college basketball fan, is the greatest time of the year! It is an all conference, single elimination tournament to declare an ultimate winner and the best team in the country. The 64-team NCAA tournament will tip off in the middle of March and will last through the beginning of April.

How are Teams Selected for the Tournament

There are 64 teams that will compete in the tournament from all over the country and from different conferences. Next week, conference tournaments will start and the NCAA bracket will start to fill up. The winner of each conference tournament receives an automatic bid to the “Big Dance.” There are 32 division 1 conferences in college basketball, so we will receive an automatic 32 teams to enter the tournament.

The main purpose of this process is to include mid-major programs that may not receive the attention or respect as the larger conferences. For the majority of these conferences, this is their only chance to punch their ticket to the tournament.

The remaining 32 teams will receive an “at-large bid” and are selected by strength of schedule, overall record, quality wins and “bad” losses. You will see more teams in the tournament from larger conferences because of the quality opponents they play and the fact that the main purpose of the tournament is to find the best team in the country.

These teams will be revealed on “Selection Sunday,” March 12th at 6 pm ET.
