The NCAA Tournament Selection Show, known as Selection Sunday, is set to begin at 6 p.m. EST on CBS.

It is then that the NCAA Tournament Committee will unveil the 68 teams that will take part in the Big Dance and compete for a national championship. There is quite a bit of uncertainty heading into this year's unveiling, especially for teams on the bubble.

Many sports pundits have noted the overall weakness of the NCAA Tournament bubble this year. Many teams have failed to really separate themselves, which should create extra drama on Sunday.

Other big drama is just where each team will be seeded. Kentucky and Syracuse have locked up No. 1 seeds, according to Committee Chairman Jeff Hathaway, with two No. 1 seeds still up for grabs. Will either Kansas or Missouri land a No. 1 seed? Will the winner of the Big Ten championship get a No. 1? And can North Carolina hold onto its assumed No. 1 seed after losing the ACC Tournament final to Florida State earlier in the day?

The good thing for college basketball programs and fans alike is that for the first time ever, the committee will explain its decisions during a live hour-long program on truTV. The committee will unveil its 1 through 68 team rankings and explain why certain teams made it into the tournament and others did not.

Follow all of the action on CBS at 6 p.m. or on CBSSports.com for live streaming options. ESPN will have hours of bracket breakdown immediately after the initial unveiling on CBS.
