The 2023 men's NCAA tournament is fast approaching with Selection Sunday just a few short days away and the annual rush to fill out brackets right around the corner.

Before the tournament field is set, there are big questions we need to answer.

Who will be the No. 1 seeds? Which teams will be on pins and needles as they wait to see which side of the bubble they land on? Which NBA prospects will be on display during March Madness?

Ahead, we've answered those questions and more to get you prepared for the start of another exciting tournament.

Who Will Be the No. 1 Seeds?

The Kansas Jayhawks top the nation with a staggering 15 Quadrant 1 wins, and with All-American candidate Jalen Wilson and freshman star Gradey Dick leading the way, they rattled off a seven-game winning streak before losing to a good Texas team on the road in their regular-season finale.

The Houston Cougars steamrolled the AAC with a 17-1 record in conference play, closing their regular-season slate with an 11-game winning streak. Houston (29-2) has played only two Quad 1 games since mid-December, but its resume is tough to ignore.

The Alabama Crimson Tide won the regular-season title in an SEC race that featured eight teams projected for a spot in the tournament field. They have a bona fide superstar in freshman Brandon Miller and lead the nation in rebounding with 44.3 boards per game. Miller spoke publicly for the first time on Wednesday since a Tuscaloosa Police Department detective testified Feb. 21 that he brought former teammate Darius Miles the gun used in the Jan. 15 shooting death of Jamea Harris.

Those three teams appear to be locked into the No. 1 seed line, with the Pac-12 champion UCLA Bruins and Big Ten champion Purdue Boilermakers set to battle for the final top seed. The Bruins are riding a 10-game winning streak into their conference tournament, while the Boilermakers weathered the storm of a field that has nine teams projected for a spot in the tournament.
