The first week of the men's college basketball season delivered early March Madness-style matchups, thrilling finishes and a few notable upsets.

It did not, however, bring any shakeup at the top of the rankings, with the top three teams remaining unchanged.

Heading into Week 2 of the season, Florida, Duke and Illinois remain in their respective spots, Nos. 1 to 3, in the latest USA TODAY Sports Coaches Poll. The Gators opened the season with a 77-67 win over Miami, while the Illini have showcased their high-powered offense, ranking No. 1 nationally in adjusted offensive efficiency on KenPom and scoring at least 100 points in each of their first two games.

UCLA began the season with a statement win over Arizona in Las Vegas, where the Bruins showcased their versatility and depth and got 21 points from Trent Perry. The Bruins' top-five win even got Mick Cronin to smile on national television, a gesture that was replicated just a few days later at TD Garden in Boston by Dan Hurley, after UConn avenged its loss to Michigan in the national championship game with an 85-77 win over the Wolverines.

The top-15 matchup between Virginia and Arkansas to close the weekend was lopsided after the opening tip in the nation's capital, as the Cavaliers took a 46-27 lead into halftime and stretched their advantage to as many as 27 points in the second half. Thijs De Ridder picked up where he left off last season, leading Virginia with 16 points and 10 rebounds.

Two ranked teams upset in the opening week were Missouri and Purdue. The Tigers fell to Saint Louis, which is once again expected to contend among the Atlantic 10's top teams, while the Boilermakers dropped a double-overtime thriller to Valparaiso after Justus McNair buried a contested buzzer-beating 3, sending Matt Painter's team to an 0-2 start.

Here's how last week's results around college basketball are reflected in the updated USA TODAY Sports Coaches Poll and AP Top 25 polls:
