Seton Hall Among Top Seeds in N.I.T. Washington and Seton Hall are No. 1 seeds in the National Invitation Tournament after they were left out of the N.C.A.A. tournament. Tennessee and Arizona also received top seeds for the 75th N.I.T., which begins Tuesday and ends with the March 29 championship game at Madison Square Garden. Drexel, snubbed by the N.C.A.A. selection committee, is a No. 3 seed. Other notable teams in the 32-team field are Miami, Mississippi State, Northwestern, Nevada and Oral Roberts. Drexel (27-6) and Oral Roberts (27-6) had the most wins among teams not chosen for the 68-team N.C.A.A. tournament. Washington finished atop the Pacific-12 standings but became the first team to win a regular-season title in a power conference and miss the N.C.A.A. tournament. The Huskies (21-10) lost to Oregon State, 86-84, in the quarterfinals of the conference tournament.
