Each weekday, our college hoops experts discuss the biggest issues, trends and themes in college basketball.
1. Which No. 1 seed is most vulnerable in the Sweet 16?
Andy Katz: Oregon. The Ducks have to get past Duke, and if they do that, they have to deal with either the player of the year in Oklahoma's Buddy Hield or co-SEC champ Texas A&M, a team that can match their length and versatility.
Myron Medcalf: Iowa State shot the lights out in Denver and Georges Niang played like a first-team All-American for the Cyclones in the opening rounds. Virginia is a great team that can dictate the pace and protect the rim in Chicago. But Iowa State will be hard for any team to beat if it continues to shoot at its current clip. That's a difficult game for the Cavs.
Jeff Goodman: Virginia. If Iowa State can stay out of foul trouble and defend at a fairly high level, the Cavs could go down.
2. Which team has the worst matchup?
Katz: Indiana. And that's only because the Hoosiers go into the Carolina game with injuries. Tom Crean said Monday he doesn't know the availability yet of Robert Johnson and Juwan Morgan. He may need a full crew to take down the Tar Heels.
Medcalf: Miami excels when it can penetrate and get buckets off its work in the paint. But that's a complicated aspiration against Nova's defense. The Wildcats are physical on the perimeter and in the paint. Wichita State had its way inside and outside against Miami as it fought back from that 27-6 deficit. A team like Nova will win by double digits if Miami's defense breaks down like that.
Goodman: Indiana. The Hoosiers are thin up front, and UNC has no shortage of big bodies to throw at them.
3. How many ACC teams will make it to the Elite Eight?
Katz: Three: North Carolina, Virginia and Miami.
Medcalf: Four: Duke, UNC, Virginia and Notre Dame.
Goodman: Three: UNC, Virginia and Syracuse.
