TUCSON, Ariz. — Arizona knocked off some quality opponents, rolled over a few overmatched ones and grinded out victories even when things didn't go so well.
The Wildcats weren't perfect during their non-conference season, but their record was and that's all that matters to them.
Nick Johnson scored 20 points, Rondae Hollis-Jefferson added 14 and top-ranked Arizona rolled over Northern Arizona 77-44 on Monday night to complete its second straight undefeated non-conference slate.
"We're good, but we can get a lot better," Johnson said. "Hey, 13-0, we'll take that. Now we've just got to get ready for conference."
The Wildcats appear to be in good shape after their latest rout against an overmatched opponent.
Arizona (13-0) played its second straight game without injured center Kaleb Tarczewski, but didn't really need him, grabbing control with a 27-4 first-half run.
Johnson got the run started and Hollis-Jefferson provided a spark starting in place of Tarczewski, grabbing eight rebounds while hustling all over the floor.
Brandon Ashley added 11 points and nine rebounds, Gabe York had 10 points and four steals, and T.J. McConnell had six assists in Arizona's 27th straight non-conference win.
One of the nation's best defensive teams all season, the Wildcats did their most damage on that end, holding Northern Arizona (3-8) to 36 percent shooting while scoring 18 points off 23 turnovers.
An overwhelming No. 1 the past two weeks, Arizona should stay atop the polls at least one more week with its next game not until Jan. 2 against Washington State.
"Being the No. 1 team in the country, you can carry it as a burden and take all of the negative connotations that you want," Arizona coach Sean Miller said. "On the flip side, we've really embraced the fact that we're the No. 1 team in the country. You can't take it from us. We earned it."
Northern Arizona had four assists and failed to get a player in double-figures scoring to become the third opponent in four games to be held under 50 points by Arizona.
No. 14 Iowa State 83, Akron 60
At Honolulu, Georges Niang scored 15 of his 22 points in the second half and Iowa State beat Akron to match the best start in school history.
Melvin Ejim had 21 points and 12 rebounds for the Cyclones, who improved to 10-0 for the first time since 1996-97 season. DeAndre Kane added 15 points and 11 boards.
Iowa State advanced to the final of the Diamond Head Classic. It will play South Carolina or Boise State for the title tonight.
Reggie McAdams led Akron (6-3) with 13 points.
