There were plenty of surprises during college basketball's first month -- as well as teams and players who validated their preseason hype. At least one freshman has exceeded his already high expectations, a preseason top-5 team has underachieved and a league that puts multiple teams in the NCAA tournament year after year has looked brutal through the first few weeks. Find out why that is and how it could be costly come Selection Sunday.

Marvin Bagley III has emerged as the most dominant player in the nation

What we thought: It would take time, and Bagley would take a back seat to senior teammate Grayson Allen this season.

What we know: Bagley doesn't need time. He is the first Duke player to post consecutive 30-point, 15-rebound games and has taken over when the game has been close. He also plays with far more poise than anyone expected. He's averaging 22 points and 11 boards through the first 11 games of his college career.

What happens next: Bagley will continue to produce at a high level, but he's logging a ton of minutes (he's averaging 33.8 over the past six games). It will be interesting to see if he hits any sort of freshman wall come February.

Arizona has been brutal

What we thought: Arizona would roll to the championship game of the Battle 4 Atlantis tournament in the Bahamas and beat Villanova to make it the storybook homecoming for 7-foot frosh Deandre Ayton.

What we know: This team -- which went 0-3 in the Bahamas -- has issues. It begins with the distractions surrounding an FBI probe, which resulted in the arrest of assistant Book Richardson, and extends to this not being a typical Sean Miller hard-nosed, defensive-minded group.

What happens next: The good news is that the Pac-12 is mediocre (and that's being kind). The Wildcats passed a big test Tuesday night, besting Texas A&M 67-64 in the Valley of the Sun Showcase. Arizona has another revealing contest against Alabama upcoming, then starts conference play against a sizzling Arizona State club.

The Big Ten is lackluster right now

What we thought: That the league would be down, but not like this. We knew Michigan State would be elite but figured there would be multiple teams in the back end of the Top 25: Minnesota, Northwestern and maybe even Purdue.

What we know: Michigan State is one of the top teams in the country, but after that, no one has really done enough to warrant a spot in the Top 25. Purdue has a couple of nice wins, including a home victory over Louisville, but the Boilermakers also lost to Tennessee and Western Kentucky in the Bahamas. Northwestern has struggled, Michigan lost to LSU, Maryland lost to St. Bonaventure, Minnesota just lost to Nebraska and the league went 3-11 in the ACC/Big Ten Challenge.

What happens next: Michigan State should cruise to the Big Ten crown, but the "résumé" teams in the league will need to step up for the conference to get more than a handful of teams in the tourney.

Gonzaga is still the team to beat in the WCC

What we thought: Saint Mary's was the favorite to win the league with Jock Landale, Calvin Hermanson and Emmett Naar all back in the fold. In fact, every coach in the league except for Randy Bennett picked the Gaels to win the conference.

What we know: The Zags may have lost four starters from last year's squad that nearly won the national title, but Mark Few's team hasn't missed a beat. Josh Perkins has stepped up in the backcourt, freshman Corey Kispert has quickly emerged as a dependable shooter on the wing and Killian Tillie and Johnathan Williams form a formidable frontcourt duo.

What happens next: This will be settled on Jan. 18 and Feb. 10. Gonzaga and Saint Mary's will play in Spokane, Washington, the first time around and in Moraga, California, in mid-February.

Kentucky is no lock to rule the SEC

What we thought: It was John Calipari's Kentucky squad, and then separation between the Cats and the next tier, which featured Florida and Texas A&M.

What we know: Kentucky isn't the front-runner to win the SEC this season. This is an inexperienced team that also lacks star power. Florida and Texas A&M looked impressive to start the year but have suffered some disappointing losses this week. The Gators nearly knocked off Duke but lost badly to Florida State on Monday. The Aggies pounded West Virginia and had no difficulty with USC on the road, although they did let a struggling Arizona team sneak by.

What happens next: Kentucky will face both Florida and Texas A&M twice, but the Aggies only have to face Mike White's Gators once, in College Station, Texas, on Jan. 2. So, we'll give Texas A&M the edge for the SEC title.

UConn will be irrelevant nationally for another season
