Men's College Basketball 2025-2026 Undefeated Teams Tracker: U-M Improves to 13-0

With conference play upon us, it's fair to start wondering which of the undefeated men's college basketball teams might actually be able to stay that way. 

Here are the six teams that have yet to log an L in 2025-2026, as well as some notable opponents that they have already taken care of and those still on the way, through Jan. 1.

The No. 1 team in the poll, Arizona remains undefeated despite facing off against ranked opponents Florida, UConn and Alabama, and in four Quad 1 games total. The Wildcats' next ranked opponent is BYU, on Jan. 26, but they have Kansas State, TCU, Arizona State, West Virginia and Cincinnati before then – all of them top-100 teams by NET ranking – and UCF, which ranks 36th in NET the toughest of the bunch.

Iowa State has No. 17 Kansas on the schedule in mid-January, but before then it faces West Virginia, 41st team by NET Baylor and Oklahoma State, so the road to the Jayhawks isn't easy, either.

Vanderbilt is yet to face a ranked opponent, but it did defeat UCF and SMU (28th in NET) during the non-conference portion of the schedule. No. 14 Alabama is their first ranked opponent, on Jan. 7, with Florida, Arkansas and Kentucky all in January as well.

Nebraska has played in just two Quad 1 matchups to this point, but it has wins against Kansas State, Wisconsin and ranked Illinois. A narrow 58-56 win over No. 9 Michigan State on Friday night made a statement for the Cornhuskers.

Michigan beat No. 24 USC, 96-66, to improve to 13-0. The Wolverines have had the fourth-most difficult schedule in all of Division I men's college basketball, which is to say that it has passed many tests already. Next up is Penn State on Jan. 6, and conference play against the likes of Wisconsin, Indiana, Ohio State,
