The Coaches Vs. Cancer Classic (now known as the 2K Sports Classic benefiting Coaches vs. Cancer) is an annual college basketball tournament played in November at the beginning of the season. The tournament was first formed in 1995 as a collaboration between the National Association of Basketball Coaches and the American Cancer Society, with help from The Gazelle Group, Inc., in an effort to raise funds for cancer research. In the current format, 16 teams from 16 separate conferences are invited to the tournament. First and second Round games are held at regional sites selected before the tournament. The semi-finals and finals are held at Madison Square Garden in New York City.
