The participating teams were selected by the National Invitation Tournament (NIT) selection committee using numerous resources such as computer rankings, results (head-to-head, chronological, last 10 games played, non-conference), and polls. The first round, second round, and quarterfinal games are held at the home court of the higher seed. The semifinal and final round are played at Madison Square Garden in New York City, New York. The 32 participating teams were announced on March 11, 2007. This is the first time since the NIT began seeding that all of the #1 seeds made the Final Four. Not only that, but both of the semifinal matches between the #1 seeds were one point games.
Thirty-two NCAA Division I teams participated in the 2007 NIT. The number of participating teams was reduced from the 40 of the recent past to 32. Teams are chosen by the NIT selection committee based on numerous resources, including "computer rankings, head-to-head results, chronological results, Division I results, non-conference results, home and away results, results in the last 10 games, polls and the coaches' regional advisory committee's rankings". The teams are then seeded according to the NIT's procedures for seeding teams. The teams are then placed into four regions: East, South, West, and North.
*Under normal circumstances, the RBC Center would be used as NC State's home court, but a concert was scheduled that night at that facility, forcing the Wolfpack to use their older arena (still regularly in use for women's basketball), Reynolds Coliseum.
A new attendance record for a NIT game was set at the Syracuse–San Diego State game in the Carrier Dome. Syracuse won the game 80–64 with the attendance total of 26,752.The old record of 23,522 was set by Kentucky in 1979.
The quarterfinals round took place March 20, 2007, and March 21, 2007. (March 22 was reserved as a backup date in case of scheduling conflicts, but none arose.) The higher-seeded team hosted each game.
The post-tournament celebration by the Mountaineers was overshadowed by a typographical error on the championship T-shirt, on which the school name was rendered as WEST VIRGINA. The vendor, 6th Man Sportswear, apologized for this mistake, and corrected the spelling for all T-shirts except those 25 printed for the team in preparation for a victory.
