Greg Gumbel's former CBS Sports colleagues are paying tribute to him Sunday. Today is a bittersweet day for the CBS Sports college basketball family. On one hand, it's Selection Sunday, which is always one of the better days of the year.

CBS found the perfect way to honor Greg Gumbel on Sunday to kick off the NCAA tournament. The network kicked off its annual Selection Sunday show with a Gumbel tribute, which featured him speaking into the camera explaining why he felt the the NCAA tournament was so special.

This year's NCAA Tournament will sound different after the death of Greg Gumbel. Remembering the legendary CBS broadcaster ahead of Selection Sunday.
