Best Bet on Favorite to Win NCAA Tournament

Duke +370

The tournament’s top overall seed got a major scare and a wake-up call in its first-round game against 16th-seeded Siena. Favored by 27.5 points, the Blue Devils narrowly avoided disaster with a 71-65 win, a result that nearly became one of the greatest upsets in March Madness history.

Duke returned to dominant form in an 81-58 victory over TCU on Saturday. The team was bolstered by the return of center Patrick Ngongba II to the rotation. He has been managing foot problems for weeks, causing him to miss the ACC Tournament and the opener against Siena.

Ngongba’s role will be vital for Duke in its Sweet 16 contest with St. John’s. He is expected to be the primary defender on forward Zuby Ejiofor, a formidable presence inside. Ejiofor posted a team-best 18 points and nine rebounds in his team’s win over Kansas yesterday.

TCU limited Duke standout Cameron Boozer to only two first-half points, but the country’s premier player recovered to lead his team with 19 points. Boozer entered the tournament as the favorite to be named NCAA Tournament MVP.

Isaiah Evans provides Duke with a significant perimeter scoring threat. He scored 17 points against TCU after putting up 16 versus Siena, making two three-pointers in each contest.

Best Bet on Sleeper Pick to win NCAA Tournament

Michigan State +3000

Head coach Tom Izzo has guided the Spartans to the Sweet 16 for the 17th time in his career. However, he is pursuing only his second national championship, with Michigan State’s last title coming in 2000.

The Spartans are led by versatile point guard Jeremy Fears Jr., who tops the nation with 9.4 assists per game and also leads Michigan State in scoring at 15.3 points per game.

Michigan State also possesses a sizable and productive frontcourt. Jaxon Kohler (12.6 ppg, 8.9 rpg), Coen Carr (12 ppg, 5.5 rpg), and Carson Cooper (11 ppg, 7.1 rpg) all average double-digit points as well.

That skilled front line will be essential to containing UConn center Tarris Reed in the Sweet 16. Reed paces the Huskies with averages of 14.2 points and 8.8 rebounds per game.

Look for Michigan State to advance past UConn, which would potentially set up an Elite Eight showdown with Duke.

Best Bet on Longshot to Win NCAA Tournament

Tennessee +6000

The Volunteers rely on their defense, which allows just 69.1 points per game. Sixth-seeded Tennessee “upset” No. 3 Virginia 79-72 to reach the Sweet 16, despite actually being favored by 1.5 points in that matchup.

Ja’kobi Gillespie led the Volunteers with 21 points, and Nate Ament contributed 16. Tennessee also boasts a signature victory over Houston from this season.

Tennessee meets Iowa State in the Sweet 16. The Cyclones may once again be missing star player Joshua Jefferson (16.4 ppg, 7.4 rpg, 4.8 apg), who sustained a serious ankle sprain in the tournament’s first round. KenPom ranks Jefferson second in the national player of the year race, behind only Duke’s Boozer.

Although the Volunteers are 4.5-point underdogs against the Cyclones, a Tennessee win would not be shocking considering their recent hot shooting. Gillespie totaled 50 points across the first two tournament games.

In yesterday’s win over Virginia, Tennessee shot 42.1% from beyond the arc and connected on eight three-pointers. Gillespie hit three of those, while Bishop Boswell knocked down four.
