2018 NCAA Division I men's basketball tournament

{{further|NCAA Division I men's basketball tournament#Current tournament format}}

A total of 68 teams entered the 2018 tournament. 32 automatic bids were awarded, one to each program that won their conference tournament. The remaining 36 bids were "at-large", with selections extended by the NCAA Selection Committee.

Eight teams (the four lowest-seeded automatic qualifiers and the four lowest-seeded at-large teams) played in the First Four (the successor to what had been popularly known as "play-in games" through the 2010 tournament). The winners of these games advanced to the main draw of the tournament.{{Cite web|url=https://www.sbnation.com/college-basketball/2018/3/14/17121546/march-madness-2018-bracket-results-highlights-scores-wednesday-texas-southern-nc-central|title=Syracuse, Texas Southern win in First Four games Wednesday night|last=Moriarty|first=Morgan|date=2018-03-14|website=SBNation.com|access-date=2019-02-24}}

The state of North Carolina was threatened with a 2018-2022 championship venue boycott by the NCAA, due to the HB2 law passed in 2016.{{Cite news|url=http://www.newsobserver.com/news/politics-government/state-politics/article140505218.html|title=NCAA gives North Carolina a deadline to repeal HB2 or lose events until 2022|work=newsobserver|access-date=March 18, 2018|language=en}} However, the law was repealed (but with provisos) days before the NCAA met to make decisions on venues in April 2017. At that time, the NCAA board of governors "reluctantly voted to allow consideration of championship bids in North Carolina by our committees that are presently meeting".{{Cite news|url=http://www.espn.com/mens-college-basketball/story/_/id/19186600/north-carolina-hb2-repeal-host-ncaa-tournament-games-2018-2020-2021|title=N.C. gets NCAA tourney sites after HB2 repeal|work=ESPN.com|access-date=March 18, 2018}} Therefore, Charlotte was eligible and served as a first weekend venue for the 2018 tournament.

{{further|2018 NCAA Division I men's basketball tournament qualifying teams}}

Four teams, out of 351 in Division I, were ineligible to participate in the 2018 tournament due to failing to meet APR requirements: Alabama A&M, Grambling State, Savannah State, and Southeast Missouri State.{{cite web|title=Division I teams face penalties, lose postseason|url=https://www.ncaa.org/about/resources/media-center/news/division-i-teams-face-penalties-lose-postseason|date=May 10, 2017|publisher=NCAA}} However, the NCAA granted the Savannah State Tigers a waiver which would have allowed the team to participate in the tournament, but the team failed to qualify.

The following 32 teams were automatic qualifiers for the 2018 NCAA field by virtue of winning their conference's automatic bid.{{cite web|title=NCAA conference tournament schedule: Tracking March Madness automatic bids|url=https://www.ncaa.com/news/basketball-men/article/2018-03-04/ncaa-conference-tournament-schedule-tracking-march-madness|publisher=NCAA|access-date=March 4, 2018}}

Kansas vacated 15 wins, including all NCAA tournament wins from the 2017–18 season after an investigation into the eligibility of Silvio De Sousa.{{cite web |title=Kansas basketball on probation as violations downgraded |url=https://www.espn.com/mens-college-basketball/story/_/id/38633740/panel-says-no-more-penalties-kansas-basketball-bill-self |website=ESPN.com|date=October 11, 2023|accessdate=April 25, 2024}} Unlike forfeiture, a vacated game does not result in the other school being credited with a win, only with Kansas removing the wins from its own record.

Per the NCAA, "Upsets are defined as when the winner of the game was seeded five or more places lower than the team it defeated." The 2018 tournament saw a total of 11 upsets; 5 of them were in the first round, 5 of them were in the second round, and one of them was in the Sweet Sixteen.

• The R64, R32, S16, E8, F4, CG, and NC columns indicate how many teams from each conference were in the round of 64 (first round), round of 32 (second round), Sweet 16, Elite Eight, Final Four, championship game, and national champion, respectively.
• The "Record" column includes wins in the First Four for the ACC, Atlantic 10, Big South, and SWAC conferences and two losses in the First Four for the Pac-12 conference.
• The MEAC and NEC conferences each had one representative, eliminated in the First Four with a record of 0–1.
• The Atlantic Sun, Big Sky, Big West, CAA, Horizon, Ivy League, MAAC, Ohio Valley, Patriot, Southern, Southland, Summit, Sun Belt and WAC conferences each had one representative, eliminated in the first round with a record of 0–1.

The Pac-12 lost all of its teams after the first day of the main tournament draw, marking the first time since the Big 12 began play in 1996 that one of the six major conferences—defined as the ACC, Big Ten, Big 12, Pac-12, SEC, and both versions of the Big East—failed to have a team advance to the tournament's round of 32.{{cite news|url=http://www.espn.com/mens-college-basketball/story/_/id/22785553/ncaa-tournament-fast-unprecedented-fall-pac-12 |title=The fast and unprecedented fall of the Pac-12 |first=Myron |last=Medcalf |website=ESPN.com |date=March 16, 2018 |access-date=March 16, 2018}}

CBS Sports and Turner Sports had U.S. television rights to the Tournament under the NCAA March Madness brand. As part of a cycle beginning in 2016, TBS held the rights to the Final Four and to the championship game.{{cite web |title=2018 NCAA Division I Men's Basketball Championship commentator teams announced |url=https://www.ncaa.com/news/basketball-men/article/2018-03-05/2018-ncaa-division-i-mens-basketball-championship-commentator |publisher=NCAA |access-date=March 5, 2018 |date=February 7, 2018}}

For the first time, TBS held the rights to the Selection Show, which expanded into a two-hour format, was presented in front of a studio audience, and promoted that the entire field of the tournament would be unveiled within the first ten minutes of the broadcast.{{Cite news |url=https://www.washingtonpost.com/entertainment/tv/selection-show-tournament-teams-revealed-in-1st-10-minutes/2018/03/06/98632aa8-215d-11e8-946c-9420060cb7bd_story.html |archive-url=https://web.archive.org/web/20180313031619/https://www.washingtonpost.com/entertainment/tv/selection-show-tournament-teams-revealed-in-1st-10-minutes/2018/03/06/98632aa8-215d-11e8-946c-9420060cb7bd_story.html |url-status=dead |archive-date=March 13, 2018 |title=Selection show: Tournament teams revealed in 1st 10 minutes |agency=Associated Press |last=Russo  |first=Ralph D. |date=March 6, 2018 |newspaper=Washington Post |access-date=March 12, 2018 |issn=0190-8286}} However, this entailed the 68-team field (beginning with automatic qualifiers, followed by at-large teams) being revealed in alphabetical order, and not by bracket matchups (which was done later in the show). The new format was criticized for lacking suspense, and the show also faced criticism for technical issues, as well as a segment containing product placement for Pizza Hut.{{Cite news |url=https://www.boston.com/sports/college-sports/2018/03/12/tbs-really-made-a-mess-of-the-ncaa-selection-show |title=TBS really made a mess of the NCAA selection show |date=March 12, 2018 |work=Boston.com |access-date=March 12, 2018}}{{Cite news |url=https://www.sbnation.com/college-basketball/2018/3/11/17107550/2018-selection-show-ncaa-tournament |title=6 ways the NCAA bracket selection show was pretty odd |work=SBNation.com |access-date=March 12, 2018}}{{Cite news |url=https://www.stltoday.com/sports/college/mizzou/media-views-ncaa-tourney-selection-show-loses-suspense-adds-immediacy/article_4b202688-4129-55d7-ae24-9ca6883ebcad.html |title=Media Views: NCAA tourney 'Selection Show' loses suspense, adds immediacy |last=Caesar |first=Dan |work=stltoday.com |access-date=March 12, 2018}}
