Louisville earned the top overall seed in the NCAA tournament Sunday, and Kansas also received a No. 1 after topsy-turvy regular season and another round of weekend upsets.
The selection committee had its work cut out after five teams swapped the top ranking in The Associated Press poll, capped by West Coast Conference champion Gonzaga (30-2) moving to the lead spot for the first time in school history.
But it is No. 4 Louisville (29-5) that leads the tournament after sharing the Big East regular-season title, then pulling off a stunning comeback to beat Syracuse in the final of the conference tournament. No. 7 Kansas (29-5) got the second top seed to be announced after defeating rival Kansas State for the Big 12 championship.
