Big Ten teams are still dancing at the NCAA Tournament with Purdue and Northwestern in action on Day 4 of the Big Dance.

Already, half of the Sweet 16 field has been filled following a dramatic and action-packed Saturday. Now, 8 more teams will find their way into the second round of March Madness throughout Sunday.

Nothing comes easy at this point in the season, but a great opportunity awaits the Wildcats and Boilermakers on Sunday. Here is a full betting preview for those B1G teams and be sure to continue tracking all the March Madness odds and trends with Tradition’s Ohio sports betting apps.

1 Purdue vs. 8 Utah State | 2:40 p.m. ET | CBS

Purdue quickly put concerns of last year’s debacle behind them with Zach Edey flexing his dominance against Grambling. He delivered a big-man masterpiece with 30 points, 21 rebounds, 3 blocks and 2 assists while shooting 11-for-17 from the field. The guards of the Boilermakers were also more efficient in this year’s tournament opener with a 9-for-24 shooting effort from 3-point range. Utah State punched its ticket to the big dance as an at-large bid from the Mountain West with regular-season wins over Colorado State, San Diego State and Boise State (twice). The Aggies are led by 6-foot-8 forward Great Osobor who averages 18 points and 9 rebounds per game. Utah State advanced with a big first-round win over 9-seed TCU.

9 Northwestern vs. 1 UConn | 7:45 p.m. ET | truTV

Northwestern delivered a roller-coaster performance in the opening round, building a 9-point lead against FAU before needing a tying bucket with less than 10 seconds to play. Once in overtime, the Wildcats ran away with the finish behind a flawless shooting performance. As a result, Northwestern gets a date with No. 1 overall seed UConn. The reigning national champions, the Huskies wasted no time jumping all over 16-seed Stetson in the opening round. UConn won that matchup 91-52 and is looking for another dominant tournament run.

UConn -14.5 (via ESPN Bet) vs. Northwestern

Northwestern’s opening win is a good one, but it did not instill a lot of confidence in the Wildcats moving forward. And that’s without getting into the lineup of the Huskies. UConn has 5 players averaging in double figures, a presence in the middle with Donovan Clingan and a group of shooters that allows the Huskies to shoot 37% from 3-point range. The Huskies have the top offense per the adjusted efficiency metric compiled by KenPom, and they’re no slouch either with the 11th defense in the country per the system. If Boo Buie and company shot the lights out in the win over FAU, I may feel differently, but that was far from the case.

Purdue -11.5 (via ESPN Bet) vs. Utah State

If UConn is a terrible matchup for Northwestern, Utah State looks like a very favorable matchup for Purdue. Osobor leads the Aggies in scoring and rebounding, but he plays like a traditional big man at just 6-foot-8. Isaac Johnson is a legitimate 7-footer who averages 15 minutes per game, but that duo will have their hands full with Edey. Utah State is also a team that does not light it up from deep while shooting 33% from 3-point range. The Aggies make up for that a bit by holding teams to 29% shooting from 3-point range, but they haven’t faced the inside-out combination of the Boilermakers. Purdue’s toughest game might have been simply getting started on the right foot in the first round, and now there’s a chance to build momentum heading into the Sweet 16.

Zach Edey OVER 38.5 points + rebounds (via DraftKings)

Zach Edey is a true juggernaut of March, and he’s the one player for Purdue who presents the safest bet. Last season in the loss to Fairleigh Dickinson, Edey combined for 36 points + rebounds (21 points, 15 rebounds), and he followed that up with an eye-popping 51 points + rebounds vs. Grambling (30 points, 21 rebounds). That performance likely pushed his second-round number to challenging proportions, but Edey is a unique 7-foot-4 monster. Edey averages 31.4 minutes per game and has the ability to play the entire second half if things are close. Purdue is also keenly aware of its recent March Madness history, so I don’t expect Matt Painter to take his foot off the gas even if things start to turn into a blowout. With plenty of rest days after Sunday before the Sweet 16, Edey is primed for another massive outing in the tournament.
