You have an opportunity to watch college basketball history Sunday. For the first time in the men's NCAA tournament, a No. 16 seed will take the court in the second round.
While UMBC attempts to continue its legendary run, No. 1 Xavier and a trio of No. 2 seeds will also be in action. Championship contender Michigan State will take on Syracuse, too.
We've covered all the major storylines, highlighted the best players in action and identified the most likely upsets for Sunday's eight-game slate.
Most Likely Upset
No. 10 Butler vs. No. 2 Purdue
The people in the desert often know what they're talking about. And according to OddsShark, Butler is only a 3.5-point underdog entering a showdown with second-seeded Purdue.
Although the Bulldogs would be respected in this matchup regardless, injury has struck the Boilermakers. Star center Isaac Haas will likely be unavailable due to a fractured elbow, which happened in Purdue's first-round win over Cal State Fullerton.
"He ran up and down today, did a few things, worked out," head coach Matt Painter said Saturday. "I don't see him playing, though."
Purdue will rely on Carsen Edwards and an excellent bunch of three-point marksmen, but if those shots aren't falling, Butler could be headed to its second straight Sweet 16.
3 Biggest Stars in Action
Miles Bridges, Michigan State
One of two potential NBA lottery picks for Michigan State (along with Jaren Jackson Jr.), Miles Bridges amassed 29 points, nine rebounds and four assists in the team's opening-round victory. He scored 19 in the second half to help the Spartans hold off Bucknell for an 82-78 win.
The sophomore will be instrumental in guiding MSU to the Sweet 16, especially if Bridges is planted in the middle of Syracuse's zone defense. That's where his passing ability could shine.
Luke Maye, North Carolina
During the 2017 NCAA tournament, Luke Maye knocked down a memorable last-second shot to lift UNC past Kentucky in the Elite Eight. Now, the junior forward is a key player for the Tar Heels.
Maye enters the second-round matchup opposite Texas A&M averaging 17.0 points, 10.1 rebounds and 2.4 assists per game. Texas A&M's frontcourt is loaded with size, but Maye can stretch the floor as a shooter. He boasts a 43.8 percent clip from three-point range.
Jevon Carter, West Virginia
The senior guard is one of college basketball's peskiest defenders. Jevon Carter holds West Virginia's single-season (103) and career records for steals (321), and he's coming off a game in which he swiped the ball six times from Murray State.
Carter racked up 21 points on 9-of-16 shooting in the first round, adding eight assists and five rebounds. His versatility and production are keys to the Mountaineers' success.
2 Games Certain to Divide Houses
Not only is Butler a prime candidate to pull an upset, but the Big East program also has an opportunity to "win the state." Butler and Purdue are the final schools from Indiana remaining in March Madness.
Of Sunday's two in-state clashes, these two schools are separated by the shortest distance.
Purdue has a more storied tradition, considering it has reached the Big Dance 28 times in the last 40 years. However, Butler has qualified for 15 NCAA tournaments over the last 22 seasons and owns a pair of national runner-up finishes in the past decade.
However, there's a little more dislike between Marshall and West Virginia.
From 1978 through 2015, the programs squared off annually. Head coaches Dan D'Antoni (Marshall) and Bob Huggins (WVU) had a mini verbal battle prior to the end of the "Capital Classic."
And now, the series resumes with the Thundering Herd confident following an upset of Wichita State.
"They're going to be ready," Carter said, per Mitch Vingle of the Charleston Gazette-Mail. "Ready to see a battle. Two very good teams going up against each other in an in-state rivalry. We'll see what happens."
1 Team Everyone Should Be Watching
If the story ended now, it would be legendary.
UMBC shocked the college basketball world when it not only upset, but also destroyed No. 1 overall seed Virginia 74-54. It was the first time in 136 games a No. 16 beat a No. 1.
"We got our butts whipped," Virginia coach Tony Bennett said on CBS after the game. "That was not even close. And that's first a credit to the job [UMBC coach] Ryan [Odom] did. Coach Odom, their offense was very hard to guard. They shot it well. We kept getting broken down and did a poor job."
Jairus Lyles paced the Retrievers with 28 points, while 5'8" guard K.J. Maura notched 10 points and three assists. Five players knocked down at least two triples for the surprise America East tourney champs, who clipped Vermont on a buzzer-beater in the conference title game.
They weren't supposed to be here. They weren't supposed to defeat Virginia. But now, they're unforgettable.
UMBC will take on Kansas State at 7:45 p.m. ET.
