The Champions Classic really got the college basketball season off to a hot start in 2019-2020.
The top four teams in the nation faced off at Madison Square Garden last week and the underdog won both matchups, providing us with some big changes in the AP Poll rankings after the first week.
The Kentucky Wildcats are now the No. 1 team in the nation after their impressive win over then-No. 1 Michigan State.
The Duke Blue Devils are right behind them at No. 2, with the Spartans, Louisville Cardinals and Kansas Jayhawks comprising the top five.
It was an overwhelming vote for Kentucky, too.
North Carolina jumped three spots to No. 6 after their two-win week, Virginia slipped into the top-10 and check in at No. 9, and the Villanova Wildcats landed at No. 10.
But the news wasn't good for everyone. VCU, who barely edged North Texas, and Purdue, who fell to Texas, got the boot from the Top 25.
We have a week of action-packed college basketball this week, too, so don't be surprised if this is looking different once again in seven days.
