​It may be early in the college basketball season, but there's already been a big shakeup among the rankings. 

Gonzaga has gone from No. 3 to No. 1 in the new AP Top 25, thanks to their ​victory over Duke on Wednesday at the Maui Invitational.

​​Prior to their loss to Gonzaga, Duke had been the No. 1 team. As talented as Gonzaga is, it's still a very impressive accomplishment that they were able to beat a very talented Duke team that includes star freshman ​Zion Williamson

So far, nobody has been able to maintain control of the No. 1 spot for long. Kansas lost it to Duke, who then lost it to Gonzaga. 

It wouldn't be surprising to see these three teams constantly moving up and down in the top three of the rankings throughout the season. For the full Top 25, see below: 

This could be a very entertaining college basketball year, which only adds to the excitement of March Madness, which will be here before you know it.
