March Madness 2018: Complete Odds and Final Four Picks for NCAA Tournament

March Madness 2018 is going to go down as one of the more maddening years to fill out a bracket. 

There's a legitimately long list of teams that could take home the title this year, which means that even if the tournament goes chock, it's going to be surprising. Looking at the odds for the entire field from OddsShark, the top 10 teams with a shot at making it includes only three of the No. 1 seeds, all four No. 2 seeds, three of the No. 3 seeds and one No. 4 seed in Arizona. 

Here's a look at the top 10:

1. Villanova +600 (1)
2. Virginia +650 (1)
3. Duke +800 (2)
4. Michigan State +1100 (3)
5. Kansas +1200 (1)
6. Purdue +1200 (2)
7. Cincinnati +1200 (2)
8. Arizona +1200 (4)
9. Michigan +1400 (3)
10. North Carolina +1400 (2)

Note: Odds reflect money won a $100 wager. For instance, a $100 bet on a team that is +600 would win $600.

That means the oddsmakers see it more likely that a 10-loss No. 2 seed in North Carolina wins the whole thing than No. 1 seed Xavier who went 28-5. So, with such a close group of contenders at the top, it's anyone's guess as to who will be in the Final Four, but here's a look at which contender could emerge from each region. 

South: Arizona Wildcats (+1200)

The South might just be the most difficult bracket to project. 

If you've picked top-seeded Virginia to go far in the tournament before, you might not be able to bring yourself to pencil them in beyond the Sweet 16. The Cavaliers have made it to the tournament five times with Tony Bennett as the head coach, and they've made one Elite Eight and have a 7-5 record in the tourney. 

The Cavaliers have always been tight on defense, and this year's unit is the most stingy in the nation, but their inability to create offense at times has been their undoing. 

There are plenty of capable contenders who could come out of the South in Virginia's stead.

Kentucky is dangerous with John Calipari's usual crop of uber-talented freshmen putting together a choppy regular season followed by a strong SEC tournament run. Cincinnati is among the most efficient teams in the country and boasts a 30-4 record. 

However, Sean Miller and Arizona are the team that look ready to break into the Final Four. Miller has taken the Wildcats to the tournament six times, has made it to at least the Sweet Sixteen all but one time and made three trips to the Elite Eight.

With DeAndre Ayton playing the role of most dominant player in college basketball, this is his most talented team yet. Ayton is one of the draft's top prospects, and he's a double-double machine, per ESPN Stats & Info:

Even with a dominant big man, the tournament often comes down to guard play, but Arizona has that, too. Allonzo Trier leads the way with 18.4 points per game on 50.8 percent shooting this season. 

The road is tough. But Wildcats might just be tougher. 

West: Xavier Musketeers (+1500)

Xavier isn't getting a whole lot of love in this region. Oddsmakers like No. 2 seed North Carolina and No. 3 seed Michigan better and have them tied with Gonzaga at +1500. 

That's probably because the analytics are not a fan of the Musketeers. KenPom has Xavier as the 14th team in the nation, mostly because of a defense that ranks just 59th in efficiency. 

However, the analytics don't account for experience, and the fact is the Musketeers have two seniors who were a part of the team's Elite Eight run last season. Trevon Bluiett is the kind of guard that can fill up the stat sheet and take over a game late, and J.P. Macura played a pivotal role in their tournament run last season. 

The other major players in the bracket all have questions. Michigan is ranked this high on the strength of their run through the Big 10 tournament, but whether they'll be able to keep that momentum after a 11-day layoff is open to question.

North Carolina lost 10 games this season. That's a lot for a No. 2 season, and while they had plenty of quadrant 1 wins, they also lost to Wofford at home. That's not a team that can be trusted on the road to the Final Four. 

The result is a team that could make it as a bit of an underdog for a No. 1 seed.  

East: Villanova Wildcats (+600)

If there is a sure thing in this tournament, it's Villanova. 

The Wildcats have the perfect combination of experience, depth and star power to put together another big run for Jay Wright.

Juniors Jalen Brunson and Mikal Bridges are among the best 1-2 punches in the nation in the backcourt, but the team has six players who average double figures. Combine that with a defense that is 22nd according to KenPom and you have a team that is built for March. 

There are threats in the region. They will likely have to beat either West Virginia or Wichita State and may have to get past Purdue in the Elite Eight, but Villanova will be favored in a matchup against any of those teams. 

The Wildcats were victims of the upset bug in the second round last year, but unlike Virginia, they've shown they can bounce back the next season. Last time Wright's squad was bounced in the second round, they came back and won the national championship the next season. 

History might repeat itself this season.

Midwest: Michigan State Spartans (+1100)

The Midwest is a brutal region with Kansas, Duke and Michigan State all sitting in the oddsmakers top five and occupying the top three seeds. 

Kansas has a big advantage simply for the fact they won't have to see Duke or Michigan State until the Elite Eight. However, an injury to Udoka Azubuike leaves them shallow in the frontcourt.

Devonte' Graham, Sviatoslav Mykhailiuk and Malik Newman will be enough to get them to the Elite Eight, but both Michigan State and Duke's size and talent in the frontcourt could be an issue. 

That leaves the winner of Duke and Michigan State to figure out who is the true favorite of the region. 

Duke is the higher seeded team, but Michigan State is a bit more experienced. Outside of senior Grayson Allen, the Blue Devils are led by four freshmen in Marvin Bagley III, Gary Trent, Jr., Wendell Carter, Jr. and Trevon Duvall. 

The Spartans meanwhile have a bunch of returning sophomores who will lead the way. Miles Bridges is the star, but Nick Ward, Cassius Winston and Joshua Langford are all integral parts of what Michigan State does. Add in freshman stud Jaren Jackson, Jr. and you have a team that has the talent of Duke with slightly more experience. 

It's been three years since Tom Izzo last took his team to a Final Four. They could be due in 2018.
