The top spot in The Associated Press Top 25 is the last place any team wants to be this season.

When Indiana lost at Minnesota on Tuesday night, it was the seventh time this season that a No. 1 team has been defeated. That's the highest number since 2009-10, according to STATS. And this season isn't over yet.

Second-ranked Gonzaga is poised to rise to No. 1 in the next poll if the Bulldogs can get through the rest of the week unscathed. If that happens, Gonzaga would be the fifth team atop the poll this season. That would be the most since 2008-09.

Analysts say that the lack of a dominant team will make this year's NCAA tournament one of the most competitive in recent memory.
