Gonzaga is the latest No. 1 in The Associated Press Top 25 men's college basketball poll that has had no stability on the top line.
The Bulldogs moved up a spot to take over for Kansas, which lasted only a week at No. 1 before losing at now-No. 10 Villanova. At the time, that had marked the first time the AP poll has had five different No. 1s before New Year's Day.
And now it's six, with the Zags (13-1) earning 54 of 65 first-place votes to outdistance Ohio State in a year with no dominant team.
Gonzaga's only loss was to No. 11 Michigan in the championship game of the Battle 4 Atlantis in the Bahamas on Nov. 29. The Zags have won five straight since, including victories at No. 21 Washington and No. 24 Arizona as well as a home win against North Carolina.
"I don't think they should be doing polls this year until March," Gonzaga coach Mark Few said after Saturday's win against Eastern Washington. "I'm serious, I mean, it's just an effort in futility at this point."
This is the eighth season to have as many as six different teams reach No. 1, though it has happened now three times in the past five years. The record for an entire season is seven, set in 1982-83 when names such as Michael Jordan and Ralph Sampson were still in the college ranks.
Michigan State, Kentucky, Duke and Louisville were the first four teams to hit No. 1. Throw in Kansas, and none has won more than twice before suffering a loss.
The Zags won't stumble this week, at least; they don't play again until hosting Detroit Mercy next Monday evening after another poll is released.
The second-ranked Buckeyes (11-1) have put together a nonconference resume likely to help their NCAA tournament seeding come Selection Sunday.
The Buckeyes had lopsided wins against Villanova and at then-ranked UNC, then beat Kentucky over the weekend in a matchup of top-6 teams. That helped them earn nine first-place votes to jump three spots Monday.
Louisville remained at No. 3 ahead of its state rivalry game against Kentucky this weekend, followed by Duke and Kansas, which fell four spots to No. 5.
Oregon, Baylor, still-unbeaten Auburn, Memphis and Villanova rounded out the top 10.
Tennessee fell out of the rankings.
AP Top 25 women: UConn is back in a familiar spot — No. 1 in The Associated Press women's basketball poll.
The Huskies moved up to the top position in the poll Monday after previous No. 1 Stanford lost at Texas on Sunday. UConn has spent more time at No. 1 than any other team in the history of the sport. This is the 243rd week it has held the top ranking.
UConn received 19 first-place votes from the national media panel. Oregon was second with Oregon State, South Carolina and Stanford rounding out the first five teams. The Ducks drew five first-place votes, Oregon State four and South Carolina one.
The Huskies (10-0) are coming off a rout of Oklahoma and don't play again until Jan. 2. Even with the huge win, UConn associate head coach Chris Dailey, filling in while Hall of Famer Geno Auriemma recuperates from surgery last week to relieve symptoms of diverticulitis, said she wasn't sure the Huskies were the best team in the nation.
"I don't know that we're the No. 1 team in the country," Dailey said. "I haven't seen enough of a lot of people. But I've known our team when we have been No. 1. This team isn't there yet. We're not really worried about No. 1 now. What we want to do is give ourselves the best chance to be in position in March."
Tennessee rose a spot to No. 23.
