March Madness games today: Breaking down Sunday's eight men's NCAA Tournament matchups

The NCAA men's basketball tournament comes at you fast. If you blink, you'll miss the field of 64 teams entering the first round cut by three quarters in the span of four days. We've reached that moment Sunday with eight second-round matchups across the country setting the Sweet 16.

There's a pair of No. 1 seeds in action, once of which must face a two-time defending champion that is trying to make tournament history. The other features one of the best players in the country that returned to action in the first round. There are also a few double-digit seeds from the Mountain West that are hoping to bust brackets by producing more surprise results.

How will it all shake out? You will have to watch. So we've provided a schedule of all the games and a breakdown of the matchups. Enjoy.

No. 1 Florida vs. No. 8 Connecticut

Florida guard Walter Clayton Jr. (1) dribbles the ball against Tennessee during the 2025 SEC tournament championship game at Bridgestone Arena.

This is where we really find out if the Huskies can somehow put together a magical run to a historic three-peat. The matchup with the Gators might be one of the most difficult in the tournament. With Walter Clayton Jr. leading a prolific three-guard attack and Alex Condon controlling the middle, it's hard to find a weakness with the Gators, who might be playing their best basketball. UConn will need its championship stalwarts Alex Karaban and Solo Ball to turn back the clock to either 2023 or 2024.

No. 1 Duke vs. No. 9 Baylor

Time/TV: 2:40 p.m., CBS

Blue Devils star Cooper Flagg looked no worse for wear Friday after his scary ankle injury in the ACC tournament. That's an ominous sign for the Bears - and potentially the rest of the field. Baylor will look to VJ Edgecombe and Robert Wright, who shoot a high volume but not great percentage from three, to keep things close. Bears forward Norchad Omier is often left alone to deal with opposing big men. That will be difficult with Duke's depth of size and length.

No. 3 Kentucky vs. No. 6 Illinois

Time/TV: 5:15 p.m., CBS

There's some history here with these programs that goes back to 1984. The Wildcats - in Rupp Arena and aided by favorable refereeing - beat the Fighting Illini with a trip to the Final Four on the line. It was after that game the NCAA forbid teams playing on their home floor in the regional rounds. This time, Illinois might have a crowd edge with the game in Milwaukee. Friday's defeat of Xavier showed how dominant the Illini can be when its 3-point shots are falling. Can it carry the momentum over against Kentucky? The Wildcats also like to rely on three, so this shapes up to be an up-tempo, high-scoring affair.

No. 2 Alabama vs. No. 7 Saint Mary's

Time/TV: 6:10 p.m., TNT

You enjoy a matchup of two teams with contrasting styles? You won't be disappointed in this one. Alabama, which leads the nation in scoring (91.1 ppg), wants to go as fast as possible. Saint Mary's wants a much slower pace with its size and defensive acumen. The Gaels are tops in rebound margin and fourth in fewest points allowed. The Crimson Tide can go hot and cold for long stretches, something that might keep them from a Final Four repeat. Saint Mary's has never reached the Sweet 16.

No. 4 Maryland vs. No. 12 Colorado State

Time/TV: 7:10 p.m., TBS

The drama surrounding the future of Terrapins coach Kevin Willard remains, though it didn't seem to have much impact on the team's play against Grand Canyon. The size of freshman standout Derik Queen will pose problems for the Rams inside. He's one of many options for Maryland, which features five double-digit scorers. Colorado State is riding an 11-game win streak that includes the Mountain West tournament that ensured a spot in the field. To pull off a second NCAA upset, star guard Nique Clifford, who leads the team in scoring, rebounding and assists, needs a better game after a sub-par tournament opener.

No. 3 Iowa State vs. No. 6 Mississippi

Time/TV: 7:45 p.m., truTV

The Cyclones didn't show any ill effects of playing without second-leading scorer Keshon Gilbert in the first round against Lipscomb. The challenge here will be different. The Rebels are known for their ability to keep games close and they won their fair share of them in the SEC. One area to watch is which team gets to the free-throw line more often. Both rely on drawing fouls and getting points when the clock is stopped.

No. 2 Michigan State vs. No. 10 New Mexico

Time/TV: 8:40 p.m., TNT

It's March, and Tom Izzo has a team capable of winning a national title. Haven't been able to say that about the Spartans for a while, but the team is loaded with depth and size to make a deep run. Winning can never be taken for granted in the tournament, however. The Lobos took down Marquette in the first round for their first NCAA win since 2012. Senior guard Donovan Dent has the ability to take over games, so expect him to draw a lot of attention from the Michigan State defense.

No. 4 Arizona vs. No. 5 Oregon

Time/TV: 9:40 p.m., TBS

These are familiar foes that this season find themselves in different conferences. Appropriately, this renewal will take place in Seattle and will have some significant stakes. The Ducks have been one of the best teams in March in the last decade as coach Dana Altman seems to get his team peaking at the right time. Nate Bittle and Jackson Shelstad will be the go-to options for their offense. The Wildcats made a run to the Big 12 tournament title. Their success in recent NCAAs with Tommy Lloyd as coach has been spotty. Caleb Love needs to avoid an off night.
