Gonzaga is the overall 1-seed in the NCAA tournament men's basketball selection committee's bracket preview, revealed early Saturday afternoon, for the second straight season.

The committee announced its top 16 seeds as of now, with Auburn, Arizona and Kansas rounding out the 1-seeds after the Zags.

"The margin between Gonzaga and Auburn is razor-thin, as is the gap between Auburn and Arizona," committee chair Tom Burnett said.

Burnett said the committee pointed to Gonzaga's wins over Texas Tech, UCLA and Texas — all of whom were selected as part of the top 16 — giving Mark Few's program the edge for the No. 1 spot.

Baylor, Kentucky, Purdue and Duke were the 2-seeds, with Burnett saying Baylor and Kentucky were right there with Kansas in the discussion for the final 1-seed.
