The Crimson Tide secured the designation after winning SEC regular season and tournament titles capped by Sunday's 82-63 win over Texas A&M in the tournament championship game. They boast the nation's third-most Quadrant 1 wins with 12 and SEC Player of the Year Brandon Miller, considered by many to be the best player in the country.
Alabama enters tournament play under a pall of controversy after police said Miller delivered a gun to the scene of a fatal shooting in January involving ex-teammate Darius Miles, who faces a capital murder charge. Miller faces no charges and has continued to play since the allegation.
Houston was announced as the second No. 1 seed ahead of a Kansas team that projected as a potential No. 1 overall seed before losing in the Big 12 tournament semifinals to Texas. The Jayhawks earned the third overall No. 1 seed, while Purdue claimed the final No. 1 seed in the East region as Big Ten champions.
Arizona, Texas, UCLA and Marquette claimed the No. 2 seeds.
