We’re just more than a month away from Selection Sunday, and the conference races are heating up.

Here are six things we learned on Saturday.

Duke has so many ways it can beat you

Outside shooting was supposed to be Duke’s weakness. The Blue Devils make 32 percent of their 3s as a team, which ranks 283rd in the country, per KenPom. And that number was lower before Saturday.

That’s because Duke went bonkers from the outside against Virginia. It finished 13-of-21 from 3-point range; R.J. Barrett was 6-for-10. Barrett has struggled with his jumper this season, but he’s never been shy about taking them. Saturday showed why. He’s a better shooter than the percentages indicate, even if his willingness to jack is detrimental some nights.

The Blue Devils are an outstanding defensive team and usually bully folks on offense with a combination of offensive rebounding and slashing. But when they’re hitting shots, it’s over for the opponent. Virginia played well on Saturday. It didn’t matter. Duke was in control from start to finish.

The Blue Devils will win it all if they play like they did against the Cavaliers.

Markus Howard is great, but the Marquette defense was the story against Villanova on Saturday

Howard scored 38 points on Saturday, and of course, Marquette wouldn’t have come close to beating Villanova without him. But we know how great Howard is — and has been the last three years. The Golden Eagles’ competent defense is new, and it did serious work against the high-flying Wildcats.

Marquette held Villanova to 65 points, 40.4 percent from the floor and 31 percent shooting from 3-point range. Sacar Anim played an excellent two-way game — he scored 18 points and was all over the place on defense. The Wildcats had scored at least 70 points in 12 of their last 14 games heading into the Marquette matchup, but the Golden Eagles held firm.

Howard plus an improved defense is a winning recipe.

P.J. Washington is one of them most underrated players in the country

Washington scored 23 points on Saturday, and he’s been incredible over his last six games, averaging 20.8 points on 55 percent shooting from 3-point land. That’s on 20 attempts, a hefty clip for a big man. Washington’s ability to stretch the floor is huge for Kentucky, which has had spacing issues over the past few years. It makes life much easier for Reid Travis, and driving lanes are open for Ashton Hagans.

Keldon Johnson has been the Wildcats’ most consistent player, and Hagans has improved the most from the start of the season to now. But don’t sleep on Washington. He’s the inside-out presence Kentucky desperately needs, and he’s been playing like a superstar lately.

Gonzaga is scary

Remember when Gonzaga-Saint Mary’s was one of the most anticipated games on the calendar? Sure, the Gaels are down this year. But they’re ranked 45th at KenPom; you’d think it would be a decent fight.
