It’s that time again — the bracket’s set, the debates are already heating up, and everyone suddenly thinks they’ve cracked the code. Duke, Arizona, Michigan, and Florida headline the field as No. 1 seeds, the First Four gets things rolling Tuesday night in Dayton, and by Thursday morning, it’s full chaos with 64 teams in play. Before you lock in your picks and talk yourself into that one upset you swear you feel coming, here’s a clean, no-nonsense rundown of everything you need — the matchups, where to watch, and a few things worth keeping in mind as this thing tips off.

First Things First: The First Four

Before the main bracket opens, four games in Dayton decide the final spots in the field. All four are on truTV. Here’s what’s on the schedule:

Tuesday, March 17

• UMBC vs. Howard for the 16 seed in the Midwest region — 6:40 PM ET, truTV

• Texas vs. NC State for the 11 seed in the West region — 9:15 PM ET, truTV

Wednesday, March 18

• Prairie View A&M vs. Lehigh for the 16 seed in the South region — 6:40 PM ET, truTV

• Miami (OH) vs. SMU for the 11 seed in the Midwest region— 9:15 PM ET, truTV

The one people are going to be locked in on is that last one. Miami of Ohio rolled through the regular season at 31-0 — didn’t lose a single game — and then got clipped in overtime by UMass in the MAC Tournament. So instead of cruising into a clean seed, they’re sitting here in Dayton having to prove it all over again. And the schedule didn’t do them any favors. Zero Quad 1 wins, not a ton of high-end tests, and the committee basically said, “We need to see it one more time.”

So now their path is about as March Madness as it gets. You go 31-1, and your reward is… an extra game just to get into the bracket, and then if you survive that, you get Tennessee waiting for you on Thursday. It’s the kind of setup that can either validate everything they did all year or make people question it all over again in a 40-minute window.

Also worth flipping over to earlier in the night: Texas vs. NC State isn’t just a solid matchup, it’s a fun broadcast too. Charles Barkley and Dick Vitale on the call together for the first time in the tournament is reason enough to have it on. Even if the game slows down, the commentary probably won’t.

Sizing Up the Bracket

East Region

Duke earned that No. 1 overall seed, and it starts with Cameron Boozer — a freshman who already looks like he belongs on an NBA floor, putting up 22.8 points and 10.3 boards a night. He’s been the engine all year. The problem? This isn’t a fully healthy Duke team. Losing Caleb Foster hurts more than it might seem on the surface, and now Cayden Boozer — Cameron’s twin — is being asked to step into a much bigger role in a tournament that doesn’t give you time to figure it out.

And that’s where this region starts to feel a little shaky for them. UConn is sitting there as a two-time champ under Dan Hurley — a team that’s been through every kind of March moment you can imagine. Yeah, they just got blown out by St. John’s in the Big East title game, but if anything, that just makes them more dangerous than it makes them vulnerable.

Then you’ve got Michigan State, and it feels like they show up in this spot every year. Tom Izzo in March is always a factor, and Jeremy Fears Jr. running the show at over nine assists a game gives them real control offensively. It’s not flashy, but it’s steady.

When you zoom out, this is probably the toughest region top to bottom. There aren’t many easy paths, and there’s a real sense that someone’s going to get knocked off earlier than expected. If you’re looking for where things could go sideways in a hurry, this is it.

West Region

Arizona comes in rolling, and it’s not just a soft run either — nine straight wins capped by knocking off Houston in the Big 12 title game. They look like a team that’s figured itself out at the right time. When you’re sitting at 32-2 with a top-five offense and defense, there’s not a whole lot to poke holes in.

But this region isn’t as clean as it looks at first glance, and it really starts with BYU. AJ Dybantsa is the kind of player who can flip a game on his own — 25.3 a night, projected top-three pick, and the type of scorer that makes even good defenses look uncomfortable.

Arkansas adds another layer to this, too. Darius Acuff Jr. didn’t just have a good year — he led the SEC in both scoring and assists, something that hasn’t been done since Pete Maravich. That’s not just production, that’s control. He can take over stretches of a game in a way that can swing a matchup fast.

And then there’s Purdue, which feels like the steady hand in all of this. Braden Smith has been everywhere for them, and they just beat a top-seeded Michigan in the Big 10 Championship.

Midwest Region

Michigan’s frontcourt is what makes this whole region feel different. Yaxel Lendeborg has been a problem all year — Big Ten Player of the Year for a reason — and when you pair that with a 7-foot-3 presence like Aday Mara, it’s just tough to match up with. They can beat you with size, physicality, and second chances, and Dusty May has them playing with a ton of confidence at 31-3 in year one.

But they’re not bulletproof, and that’s where Iowa State comes in. If you’re looking for the team most likely to knock them off, this is the one people keep pointing to. Otzelberger’s group doesn’t just defend — they disrupt. They force turnovers at one of the highest rates in the country, and Michigan has had stretches all year where they get a little loose with the ball. That’s the kind of matchup that can snowball quickly if it starts going the wrong way.

Then there’s the spot everyone’s circling for an upset. Texas Tech losing JT Toppin to a torn ACL late in the year changed the feel of their entire team, and you saw it right away with three straight losses heading into the tournament. That opens the door for Akron in a big way. They’ve won 19 of their last 20, they’re playing with confidence, and this is exactly the kind of 12-over-5 setup people look for every year. If you’re hunting for a bracket swing game in this region, that’s probably the one.

South Region

Florida comes in as the defending champ, but this doesn’t feel like your typical No. 1 seed run. They just got run off the floor by Vanderbilt in the SEC Tournament, and now that same Vanderbilt team is sitting right here in this region as a 5 seed. That’s the kind of detail that sticks with people when they’re filling out brackets. It doesn’t mean Florida can’t flip the switch, but it does make this feel a little more fragile than you’d expect from a top line.

Illinois is the team that can really mess with this whole setup. They’ve got the No. 1 offense in the country per KenPom, and it’s not just empty numbers — they can score in bunches. Keaton Wagler is the name that keeps coming up, and for good reason. The freshman’s already had a 46-point explosion against Purdue.

And Nebraska is the wild card that people won’t know what to do with. Nine tournament appearances, zero wins — and now they’re a 4 seed with a very real path to finally breaking through. It’s one of those situations where you’re either buying into the momentum or you’re waiting for history to show up again. Either way, they’re going to be one of the more interesting teams to track in this region.
