With just one football game on the slate Saturday -- Army finally beat Navy! -- college basketball stepped out from the shadows to steal the show. It did not disappoint.

Here are 10 big takeaways from a full and informative day of college hoops:

1. Grayson Allen looks fully healthy, and Duke looks even more frightening

That's a scary thought. Duke hit an unfortunate skid in the preseason with injuries, most notably to their freshmen. But Grayson Allen has been among that group, too.

Allen sat out last game against Maine to nurse a nagging injury to his foot/toe. But against UNLV on Saturday, he appeared to be back to his old, peppy self. HELLO.

Allen finished the night with a career-high 34 points in Duke's 94-45 win. If Saturday's performance indicates his return to health, then Duke's ability to throw out All American-level talent all over the floor gets all the more ridiculous. From Allen to Luke Kennard to Amile Jefferson to Jayson Tatum, any one of those four dudes can beat you almost single-handedly on a given night.

Oh, and Harry Giles -- you know, just another virtual lock lottery pick -- is reportedly close to returning as well,

Also, it was fun to see Duke and UNLV finally play again. It had only been 25 years, guys. UNLV ... that's a rebuild job, to say the last. It might be a few years before the Runnin' Rebels crack back into the national polls.

2. Notre Dame can play with anyone

It's entirely possible we learned more about Notre Dame in their loss than we did about Villanova in their win over the Irish. We know Villanova is good -- really. It is No. 1 for a reason. But Notre Dame, who entered today at 9-0 and ranked No. 23, put up a huge fight down to the wire. The Irish got off to a great start behind plays like this from -- who? -- Matt Farrell. He might be one of the most improved players in America.

Even with their loss, the Irish proved they can hang with the best of the best. The game required a 37-point heroic showing from Villanova's Josh Hart to will the Wildcats to get the win. Mike Brey and his veteran Notre Dame squad will be dangerous this year. Perhaps top-five in the ACC, but we've got to see a little bit more. This was the first real test for ND, and it passed, but more examination is needed before we can definitively declare the Fighting Irish as an elite team in the elite conference.

3. Carlton Bragg's disturbing suspension was the backdrop on Kansas' day

Sophomore forward Carlton Bragg was suspended indefinitely by Bill Self after being charged with battery against his girlfriend earlier this week. Bragg sat on the bench in street clothes. Kansas did just fine without him in an 89-72 win over Nebraska.

Beyond the suspension: Udoka Azubuike and Landen Lucas are commanding a majority of the minutes in the post. And Dwight Coleby may see a bump in minutes in Bragg's absence.

Who knows what happens with Bragg's case? They will miss the depth in his absence. But you get the feeling that they will be just fine without him moving forward. It wouldn't be a surprise if he doesn't make a return any time soon. The charge is serious, and getting that matter cleared up is a lot more important than his eligibility on the floor in the short-term.

4. He's got a lot of competition, but no player is more fun to watch than UCLA's Lonzo Ball

Ball was everything you want to see -- but seldom do -- from a college basketball player against the likes of a team like Michigan. He played loose. He has a child-like enthusiasm. He drives and dishes. And best of all, he'll pull the trigger on a 3-pointer from Chino Hills if he feels like he has the hot hand.

What a treat he is. If you aren't watching him every single night he's on TV, you're missing out. He finished with 19 points and the Bruins shot a ridiculous 67 percent. The whole team is so fun, but it feels like that energy, and the energy surrounding UCLA's revival, comes form Ball.

By the way, UCLA and Michigan played a ridiculous game, a game wherein they combined to hit 29 3-pointers. At halftime, the teams were a combined 22 of 30 from deep.

5. Lauri Markkanen is now getting help, and Arizona's not going anywhere yet

Markkanen, a 7-foot unicorn who can do it all, has rightfully received the attention for Arizona. But it was another freshman, slender point guard Kobi Simmons, who stole the show against Missouri. The Wildcats lost Parker Jackson-Cartwright to an injury, and in his place, Simmons has emerged as a reliable scoring threat. He'll be vital to keeping Arizona as a top-30 team. Missouri's not that good, but these are nice gains for Simmons.

The freshman's confidence is sky-high and he was at his best showing aggression and attacking the rim against Mizzou as he set a career high with 19 points. Given Arizona's injury struggles, it's a much-welcomed sight for Sean Miller, who's looking to replace a lot of production that is sitting on the bench.

6. Josh Hart is the leading candidate for national player of the year

Norlander wrote it earlier, and it's hard to argue. We are only a month into the season, but Hart has been the best player on the No. 1 ranked team. By that measure for many, he's leading the race. Hart dropped a cool 18 points in the first half against Notre Dame on Saturday, then followed it up with a 19-point outburst in the second half. He single-handedly kept his team in the game. He did it by attacking the basket and forcing Notre Dame on its heels.

Last week he became the first Villanova player to record a triple-double in more than three decades. And secretly, the Cats are riding a 16-game winning streak that goes back to the 2015-2016 season. There's really no debate that he should be the leading candidate for national player of the year.

7. You might've missed it, but Josh Jackson's bounce-back ability is a key to his appeal

Josh Jackson may very well end up as a top-3 pick in the 2017 NBA Draft. He's a very athletic, bouncy wing who has the defensive prowess of an NBA player already.

As a freshman, he seems to be handling the college game just fine. But naturally it does come with some hiccups, as you can see from this botched alley-oop against Nebraska.

The immediate words after the miss from the commentator? "Bill Self is not happy."

Bouncing it off the glass wasn't his idea, but a miss is still a miss. He put it behind him quickly, though, bouncing back with a punctuation dunk that helped seal the win over the Cornhuskers. There's still a learning curve, seemingly as with all freshmen. But the game seems to be slowing down for him -- just in time for conference play.

8. Marquette missed its one big chance by losing to its hated rival

Marquette could've made a big statement with a home victory over a good Wisconsin team, but instead Bucky won 93-84 and will remain ranked come Monday.

So for the 7-3 Golden Eagles, this is likely what's facing them the rest of the season: In order to get into the NCAA Tournament, they will either have to win the Big East tourney in March, or they'll have to finish in the top four of the league's standings, because they'll need a whole lot of wins against tournament-caliber opponents in order to earn an at-large bid. Right now, Marquette's best Ws are against Vanderbilt and Georgia.

As for Wisconsin, it's 9-2 with wins over MU, Oklahoma and Syracuse. Nigel Hayes (17 points, nine rebounds, four assists, three steals) looked tremendous, even playing the role of playmaker nearly perfectly. Bucky had six players score double figures. Bronson Koenig sank four 3s. There are times when you watch Wisconsin run its offense and it's so efficient, you wonder why more teams don't try to emulate it.

9. Wichita State is almost certainly going to the NCAA Tournament again this season

The Shockers are 9-2, ranked 17th in KenPom and beat Oklahoma 76-73 in OKC on Saturday night. Gregg Marshall lost the two best players he's ever coached, Fred VanVleet and Ron Baker, and yet this program continues to chug. WSU is likely to finish 11-2 in non-conference play, as they get Oklahoma State in Wichita next Saturday, then welcome South Dakota State to the Round House three days before Christmas. Then Missouri Valley play starts Dec. 28.

The reason why Wichita State is so good again isn't just the defense. Yes, Marshall's team is damn good without the ball. But the players he's able to get into his program are fun, athletic and can do things like this. Say hello to Daishon Smith, who might not even be the best dunker on this team.

10. Northern Iowa's best player scored 38 points -- and all of them came in the second half

Within the Missouri Valley, Wichita State will get a push from Illinois State and, again, Northern Iowa. See, UNI probably has the best player in the league. His name is Jeremy Morgan. And in UNI's home game against North Dakota on Saturday, Morgan got shut out in the first half.

Then this happened.

I'm not sure how often any player in the past 20 years has scored 38 points in a half at the D-I level and against a D-I team, but it wouldn't shock me if it hasn't happened more than four or five times.

UNI is just 5-4, while Morgan is averaging 18.1 points.
