NCAA Tournament: Updated National Championship Odds Entering Sweet 16

The March Madness field has been cut from 68 teams to 16 in just a handful of days.

With that, the championship vision for each of these squads is starting to feel a whole lot more real. Making the Sweet 16 is a significant accomplishment, and at this point, teams are no longer just shooting for the stars. They have a legitimate chance. They are just a handful of wins away from turning a championship dream into reality.

There's been no shortage of upsets, but most of the top seeds and favorites from before the tournament started are still standing.

With 16 teams remaining, there are clearly some squads with short odds that have emerged as favorites, while others remain massive long shots. But this is March Madness for a reason. Anything can happen.

As these games tip off over the next few days, do not be surprised if some of the teams sitting in the bottom half of the odds board find a way to advance to the Elite Eight, the Final Four, or even beyond.

Here’s the latest look at the odds via FanDuel.

• Michigan: +300
• Arizona: +330
• Duke: +440
• Houston: +750
• Purdue: +1500
• Illinois: +1500
• Iowa State: +1800
• Connecticut: +2700
• Michigan State: +3000
• St. John's: +3000
• Arkansas: +4000
• Tennessee: +5500
• Nebraska: +6000
• Alabama: +10000
• Iowa: +10000
• Texas: +20000

To no surprise, Michigan, Arizona, and Duke sit at the top of the board as the three No. 1 seeds that have looked the best to this point. From there, Houston has as good a chance as anybody to win it all, even if the odds reflect that tier a little differently. Any of these teams winning it all would not be surprising, nor would it be if the entire Final Four featured these teams.

Just behind that group is a cohort of teams like Purdue, Illinois, and Iowa State, all of whom entered the tournament as high seeds and still feel very capable of making something happen over the next two rounds. They have the talent, so now it's about showing up and giving their best punch when it matters most.

After that, there’s a larger tier that includes UConn, Michigan State, St. John’s, Arkansas, Tennessee, Nebraska, and Alabama. Relative to the rest of the field, those teams are long shots, but they still have enough talent to make things interesting and put together a real run.

Then finally, you have Iowa and Texas at the bottom of the board. These are teams that were not really expected to be here, had to pull off upsets to reach this stage, and have the longest odds for a reason. Still, they’ve already made it this far, and that is the beauty of March Madness. Once you get to this point, anything can happen. Iowa and Texas are effectively the pair of Cinderella teams remaining relative to the field.

In all likelihood, at this point, it will be a No. 1 seed that wins the entire NCAA Tournament. They've looked strong in each of their first two matchups and represent a quarter of the remaining field. The pathway matters too, which is likely where oddsmakers have the slight variations in the odds between the four No. 1 seeds.
