The number of unbeaten teams in college basketball is down to three.

No. 6 Nevada dropped from the ranks of the unbeaten with an 85-58 loss at New Mexico, leaving No. 2 Michigan, No. 4 Virginia and No. 19 Houston as the only teams with unblemished records.

The Wolf Pack staged a stunning comeback at The Pit in 2017, overcoming a 14-point deficit with 1:10 left to top the Lobos 105-104 in double overtime.

New Mexico (8-6, 2-0 Mountain West) took control from the start Saturday night, building a double-digit lead and, this time, maintaining its advantage to send its fans storming onto the court. The Wolf Pack (14-1, 0-1) had matched the best start in program history.

“The one thing we’ve prided ourselves on was really competing until the end,” Nevada coach Eric Musselman said. “We didn’t play hard tonight. We splintered and we came apart. We have to regroup and try to play better next game.”

Michigan (14-0, 3-0 Big Ten) continued its impressive follow-up to last year’s national title-game run by rolling over Penn State 68-55. The Wolverines faced a stiff test later today, hosting No. 21 Indiana.

Virginia (13-0, 1-0 ACC) put on another defensive show against No. 9 Florida State, holding the Seminoles to 15 field goals in a 65-52 win .

Houston (14-0) opened its AAC schedule with a 74-56 win over Tulsa to extend the nation’s longest home winning streak to 27 games. The Cougars played Memphis later today.

CYCLONES RISING

Iowa State coach Steve Prohm had to bide his time early in 2018-19 as the Cyclones opened the season with eight scholarship players due to injuries.

Now that the Cyclones are finally healthy, they’re showing what they can do.

Forcing 24 turnovers, Iowa State had its most lopsided win over No. 5 Kansas in 46 years with a 77-60 victory in Ames on Saturday. The Cyclones (12-2, 2-0 Big 12) were up to No. 18 in the AP Top 25 early in the season before dropping out. The win over the Jayhawks could get them back in.

SPARTAN STRONG

No. 8 Michigan State picked up a few quality wins early in the season, with its only losses coming against Kansas and Louisville.

The Spartans (13-2, 4-0 Big Ten) picked up their best win yet, knocking off No. 14 Ohio State 86-77 despite being without injured guard Joshua Langford. Michigan State has won eight straight heading into Tuesday’s game against Purdue.

WINNING WOLFPACK

North Carolina State has been one of college basketball’s biggest surprises so far this season.

Picked to finish eighth in the ACC, the Wolfpack (13-1, 1-0) are off to their best start since the 1973-74 team won the NCAA title.

N.C. State won its lone game this week, holding off Miami 87-82, and its only loss was to then-No. 22 Wisconsin in Madison.

The Wolfpack face a huge test on Tuesday, playing No. 15 North Carolina.

STREAKING HOKIES

Another ACC team is off to its best start in years: No. 10 Virginia Tech.

After trailing at halftime, the Hokies (13-1, 2-0) rallied to beat Boston College 77-66 on Saturday for their eighth straight win. Virginia Tech is off to its best start since the 1982-83 team opened 14-1.

The Hokies have a shot at their highest ranking ever (No. 8) on Monday after Kansas, Nevada and Florida State lost.

ZION’S DUNK

Duke freshman Zion Williamson seems to have two or three highlight-reel dunks a game. He may have outdone himself against Clemson on Saturday.

After poking the ball free near midcourt, Williamson launched 360 degrees in the air, cocked his arm back and had his eyes nearly even with the rim as he threw down a thunderous. The dunk brought the Cameron Crazies and some of Williamson’s teammates off their feet — maybe even a few fans from their couches.

POLL CHANGES

The bottom half of the AP Top 25 could see some changes in Monday’s poll.

No. 24 Nebraska, which moved back into the poll last week, lost to unranked Maryland and could fall out. So could No. 25 Iowa after losing by 16 to Purdue.

No. 23 Oklahoma lost to No. 5 Kansas, but bounced back with a win over rival Oklahoma State, so the Sooners may hold steady.

Defending national champion Villanova could move back into the poll after beating Seton Hall on Saturday.
