Printable NCAA Tournament Bracket 2018: Where to Download Complete Bracket

College basketball fans across the country rejoiced Sunday, as the brackets for the 2018 NCAA men's basketball tournament were unveiled.

The Virginia Cavaliers, Villanova Wildcats, Xavier Musketeers and Kansas Jayhawks occupy the four No. 1 seeds, with Virginia the top overall seed. Below is the full tournament bracket, and a printable version is available on NCAA.com:

One of the biggest questions heading into this year's tournament is whether Virginia finally reach the Final Four under head coach Tony Bennett.

Virginia has averaged 28 wins a season over the past five seasons. Over that time, the Cavaliers claimed three ACC regular-season titles and an ACC conference tournament crown. Under Bennett's watch, Virginia has become a perennial powerhouse in college basketball again.

Despite that, the Cavaliers haven't advanced further than the Elite Eight since Bennett arrived in 2009. That's not necessarily an indictment of Bennett or Virginia, either. One would just expect the team's luck to turn around at some point in the NCAA tournament.

Beating North Carolina in the final of the ACC tournament illustrated the Cavaliers' strength.

Along the same lines, the 2018 tournament could represent a breakthrough for Xavier head coach Chris Mack. 

With the Gonzaga Bulldogs making last year's Final Four, the Musketeers are arguably the most consistent program in college basketball without an NCAA tournament semifinals appearance on their resume. It was somewhat ironic Gonzaga had to go through Xavier in the Elite Eight in order to get there a season ago.

Experience will be a big strength for the Musketeers. Their top three scorers, Trevon Bluiett, J.P. Macura and Kerem Kanter, are all seniors. Kanter didn't play for last year's Elite Eight team, but he got some NCAA tournament experience under his belt with the Green Bay Phoenix in 2016.

Big things will be expected of Bluiett. The senior guard is averaging 19.5 points, 5.7 rebounds and 2.5 assists a game this season, and he showed he doesn't shy away from the big stage when he averaged 21.3 points in Xavier's four NCAA tournament games in 2017. 

A Final Four appearance would be the perfect way to cap off what has been an excellent college career.

If recent history is any indicator, fans can count on one big surprise in this year's Final Four. For five straight seasons, a team seeded seventh or lower has advanced to the national semifinals, with the No. 7 Connecticut Huskies winning it all in 2014.

The Clemson Tigers are largely overshadowed by those at the top of the ACC, but they sit 10th in the RPI and 19th on KenPom.com. The Tigers' defense has been a strength all season. Clemson is 29th in points allowed (65.8 per game) and 35th in opponent field-goal percentage (41.0).

Donte Grantham's season-ending ACL injury has put more pressure on Marcquise Reed to be the team's offensive spark, though, which could be troublesome for Clemson.

According to Sports Reference, Reed shot 50.0 percent in the Tigers' six December games. His field-goal percentage then slipped to 42.5 percent in January, 40.4 percent in February and 37.8 percent in March. The junior guard was 2-of-14 from the field in the Tigers' ACC tournament defeat to Virginia.

Generally speaking, Reed's decline in offensive efficiency is a concern for Clemson.

The Missouri Tigers could be a major wild card this season as well. Highly touted freshman Michael Porter Jr. played only two minutes in the team's season-opening victory over the Iowa State Cyclones before suffering a back injury. He then underwent surgery that has kept him for nearly the entire season.

Porter returned for the SEC tournament, scoring 12 points and grabbing eight rebounds in the Tigers' second-round defeat to the Georgia Bulldogs.

Porter will want to make the most of what's likely to be his only NCAA tournament appearance. Not only does the hope of a deep tourney run provide a source of motivation, but he'll also want to bolster his NBA draft stock after it took a hit resulting from his injury problems.

Missouri won 20 games despite Porter's absence, so the Tigers are a solid team. But a healthy Porter playing at his best could make them really dangerous in the early rounds.

Staying in the same conference, the Alabama Crimson Tide reached the SEC tournament semifinals largely through the efforts of freshman guard Collin Sexton. Sexton hit the game-winning shot in a 71-70 second-round win over the Texas A&M Aggies, and he scored 31 points in Alabama's 81-63 upset of the No. 16 Auburn Tigers.

The Crimson Tide then lost 86-63 to the Kentucky Wildcats despite Sexton's 21 points, so Sexton can only take Alabama so far on his own. Still, he may be able to help Alabama notch one surprise elimination before the team bows out of the Big Dance.

Even if Porter and Sexton are unable to lead their teams to victories in the early rounds, fans should enjoy what's left of their college basketball careers.
