The team with the best record in the best conference.
SEC BY FAR
It isn't
The University of Kentucky Wildcats has the best winning record in NCAA history, with a 1876-577-1 record since 1903.
There are 65 teams selected to play in the NCAA Men's Basketball tournament. 30 teams are selected by winning their conference tournaments. The Ivy League conference winner is also selected even though they don't have a conference tournament. The other 34 teams are selected by the NCAA selection committee. The selection committee is made up of ten athletic directors and conference commissioners from Division I men's and women's basketball. With a mix of Major and "mid-major" schools being represented. Generally, any team in the top 25 is assured a seed in the tournament. Many of the teams not assured of a spot in the tournement do not know if they will be selected until the selections are announced on TV on Selection Sunday. The women's tournament selection process is basically the same as the men's selection process.
1.) They can automatically qualify by winning their conference tournament title or, in the case of the conferences that don't have conference touraments such as the Ivy League, they can qualify by winning their conference's regular season title. 2.) By having a high enough RPI to get one of the 33 at-large bids. The RPI considers the team's record and their performance against quality (or not-so-quality) opponents. 3.) By not getting caught violating the NCAA rules.
Four times a 15 seed has won their first round game and none of them advanced past the second round of play.
It depends upon the league/sport. In the NFL, for example, the team with the best overall record wins their division. In the event of a tie, the division record acts as the tiebreaker. I believe the best conference record wins the conference in NCAA Football, regardless of overall record. Then there are the league like the NHL, where a team earns 2 points for a win, 1 for a tie or post regulation loss--with the team accumulating the most points winning their division/conference.
