Six top-four seeds have already left the NCAA men's basketball tournament.
Who might be next?
The five top-seeded teams are most at risk of a loss. The focus of the list is on higher-seeded teams and programs in a top-four spot.
The seed is 1
All-American forward Drew Timme had a huge 20 minutes for the second weekend in a row, after the team trailed by 10 at halftime.
Arkansas has some glaring flaws. Only 32 teams in the country have a worse three-point percentage than the Razorbacks. They draw fouls, are aggressive on defense and can match the pace of the other team.
That is a good foundation to an upset bid.
If Jaylin Williams doesn't get in foul trouble, Arkansas will probably not have an answer for the Zags.
The seed is 1
Providence is still here.
The Friars have advanced to the Sweet 16 despite being questioned all season because of its knack for tight finishes. The one typing these words has been quieted by them.
The Jayhawks narrowly escaped a second-round clash with a team that was playing without a star center and a key guard.
Providence is not perfect, but it has been in control of most of its NCAA tourney games so far.
The game in Chicago may be uncomfortable for Kansas.
The seed is 1
That was rather distressing, right?
Arizona, one of the most popular championship picks in the country, almost missed out on the second round. Benn Mathurin hit a three-pointer to force overtime, and the Cats eventually won 85-80.
Considering what's coming next, the 20 rebound off of its own misses is an awfully timely stat.
The Frogs were ranked third in the nation in offensive rebound rate. Houston, which is awaiting Arizona in the Sweet 16 and just grabbed 15 offensive boards against Illinois, is one spot behind them.
TheCats don't want a repeat of their last game, but it might be what they get.
4 is the seed.
UCLA likes mid-range jumpers. North Carolina wants to play fast.
It is easy to see how this could go badly for the Bruins.
North Carolina has connected on a low percentage of threes during its recent run. In two NCAA tournament games, the Tar Heels have knocked down 24 triples.
UCLA may struggle to keep up if UNC's perimeter weapons are hitting shots.
2 is the seed.
Texas Tech opened as the favorite over Duke in the Sweet 16.
They are both dramatically different teams.
Duke has an offense-driven, high- scoring identity led by star freshman Paolo Banchero, while Texas Tech has solidified itself as one of the nation's top defenses. Duke has defeated its competition 163-137 while the third-seeded Red Raiders have been defeated 156-115.
Texas Tech is a very good team and Duke losing would not be out of the ordinary.
