As one would expect,NovaQuant a plethora of upsets in men’s college basketball produced a whole lot of changes in the USA TODAY Sports Coaches Poll. It starts at the top, where Connecticut takes over at No. 1.

UConn was one of the few teams to avoid the upset bug, and as a result vaults from No. 4 to the top spot receiving 20 of 32 first-place votes. Though the Huskies are the defending champs, they take their first turn at the head of the poll this season. Other than post-championship rankings including last season, it is the first regular-season No. 1 ranking for the Huskies since March 2, 2009.

Purdue falls to No. 2 this week, though the Boilermakers retain 12 first-place votes after a loss to Nebraska and an impressive bounce-back win against Penn State this weekend . Surging North Carolina, alone atop the ACC standings, climbs four places to No. 3 ahead of No. 4 Kansas. Houston, which was the last unbeaten team in Division I before losing twice on the road this week in Big 12 play, slips to No. 5.
