Check back throughout the night for more insights on the latest results.

Duke vs. Virginia

Entering the day, Duke sat at No. 1 overall in bracketology, with Michigan already finished for the weekend with a decisive win over Top 10 competition. Virginia had a chance to enter the mix for a 3-seed jump from their current spot on the 4-seed line.

The ACC stakes were also present, as the conference’s two top teams faced off with just a week left in the regular season. Virginia had a chance to tie the Blue Devils in the standings with the head-to-head advantage.

Duke pulled away throughout the game and left their mark. The Blue Devils have clinched at least a share of the ACC regular season title, with the inside track to the top seed in the conference tournament. They also maintain their spot as the favorite to land the No. 1 overall seed in the NCAA Tournament.

Virginia will not suffer a significant fall, staying in the 4-seed conversation regardless of results around them. However, it is a missed opportunity for the Cavaliers to enter the 3-seed line with potential to keep climbing into preferred position in March.

Arizona vs. Kansas

Entering the day, Arizona remained firmly entrenched as the No. 3 overall seed in bracketology. Kansas, meanwhile, sat on the 4-seed line with room to move up or down depending on the day’s results. With neither team in danger of dropping a seed-line, there was only room to improve.

It was also an important game for the Big 12 standings, as Arizona looked to clinch at least a share of the regular season title. Kansas entered the day in a four-way tie for the second position with others in the mix facing off against each other.

Arizona created a big lead early, showing why they are above the pack with Duke and Michigan as the only teams left with the No. 1 overall seed within reach. Despite a comeback effort, they pushed the lead back out in a move which will keep their analytic metrics strong as they look eliminate any chance of falling to the fourth 1-seed spot.

Kansas will likely shift slightly down the board on the 4-seed line, no longer in the top spot. The Jayhawks will get more opportunities to make a jump onto the 3-seed line in the final week of the regular season and into the conference tournament.

Iowa State vs. Texas Tech

Iowa State entered the day on the 2-seed line, clinging to the No. 6 overall seed as Florida pushed to bypass them and make themselves one of the favorites to clinch the final 1-seed spot. Still in the mix, the Cyclones needed this win to make their case. Texas Tech entered the day looking to prove once again that they still deserve a spot in the Top 16 without star forward JT Toppin.

It was a massive matchup for the Big 12 standings as well, with both teams involved in a four-team tie for second place entering the final three games of the regular season. Seeding could prove vitally important to creating a path toward the conference championship in a loaded field.

Texas Tech came away on top, adding the impressive Q1 road win to their resume and locking themselves into the 4-seed line or better moving forward. The Red Raiders have held together strong results even without their All-American leader.

Meanwhile, Iowa State takes a hit and now sits on the edge of the 2-seed, 3-seed line along with Houston and Illinois which have taken multiple losses over the past seven days. The door is now open for some 3-seed teams to make a move up the board.

Tennessee vs. Alabama

Tennessee entered this game as a 5-seed in bracketology, with a chance to enter the debate for a Top 16 overall seed with a win. Alabama meanwhile, continues to hold onto the 4-seed and needed the result to hold off multiple SEC teams in the mix for their position.

The game also had SEC Tournament impact, as the conference standings come down to the final week with Alabama sitting in a tie for second and Tennessee one game back in fourth. The ability to lock up a double-bye created big incentive for both sides.

Alabama only led in the final seconds, but the late comeback was plenty to lock themselves into the Top 16 for Sunday’s bracketology update. The Crimson Tide will also enter the SEC Tournament in good position to keep building stock and hold onto a 4-seed position.

Tennessee will not drop far as a result, particularly with the results below them to this point. The Volunteers do lose their best chance at find the 4-seed line, but can do anything with a deep SEC Tournament run in the coming weeks.

Bubble movement

The NCAA Tournament bubble continues to shrink with just one week left in the regular season, as more teams can consider themselves safely in the mix. However, there is still plenty opportunity for those still near the cutline to make ground.

• Missouri is closing in on an NCAA Tournament lock after defeating Mississippi State by 24 points, which will see their analytic numbers take another leap. Entering the final week, losing out through the SEC Tournament in blowout fashion is the only threat left to their bid.
• Cincinnati is likely too far off the cutline to make the NCAA Tournament without a deep run in the Big Ten Tournament, but a dominant win over Oklahoma State will keep them in the mix. With multiple Q1 opportunities hypothetically on the table, there is a thin path left.
• New Mexico knocks off SDSU in a critical battle between two teams likely to land somewhere between the Last Four In and the First Four Out. The Lobos and Aztecs have now split the season series, leaving little to between them in the comparison.
• California suffered a devastating loss for their resume as a First Four Out team, potentially dropping them into the Next Four Out group after a loss to Pittsburgh. They are running out of time and opportunities in the ACC.
• Texas comes out on top against Texas A&M, creating some cushion between themselves and the Last Four In conversation entering the final week of the regular season. The Aggies, however, are now on the edge of that debate, although they still have a gap to the cutline.
• USC sees its losing streak grow to five, making a late charge back toward the right side of the bubble look increasingly unlikely thanks to Nebraska. The Trojans will likely need more than a regular season finish to make it back into the conversation.
• West Virginia picked up a massive win over BYU at home to keep their NCAA Tournament hopes alive as they remain in the mix of More To Do teams that have not seen the door shut completely.
• Stanford continues to add to its resume with another impressive win over SMU. However, they remain in the More To Do category because of lagging analytic numbers which do not match up with the rest.
