Currently a total of 31 teams earn automatic bids into the NCAA Tournament and the remaining teams get at-large bids except for one bid that goes to the regular season champ of the Ivy League. Let’s consider a few facts about NCAA March Madness history and March Madness betting.
NCAA March Madness history shows that teams are seeded 1-16 with the #1 facing the #16, the #2 versus the #15 and so on. Since there are 65 teams, the 64th and 65th teams play a play-in game on Tuesday before the tournament begins on Thursday to get down to a total of 64 teams. NCAA March Madness history shows us that the first round games are played on Thursday and Friday with second round games on Saturday and Sunday. This gets the field down to the Sweet Sixteen. The next Thursday and Friday the field is narrowed to the Elite Eight and then narrowed to the Final Four on the weekend that March Madness betting gamblers love. The following weekend the Final Four gets underway for gamblers that love March Madness betting and the Championship game is played on Monday.
