Every year there are teams that have a beef with the NCAA Tournament selection committee. This season will be no different. But most of the teams on the list below had major flaws. Low RPI, bad non-conference schedule, etc...
Rhode Island - The Rams (23-9) certainly had a beef, but losses to St. Bonaventure on February 27 and a terrible loss to UMass on March 6 did them in. They advanced to the Atlantic 10 semifinal, but were destroyed by Temple, 57-44. Not too mention the only decent non-conference win came against Oklahoma State on January 2.
Virginia Tech - The Hokies (23-8) might have the biggest beef. They finished 10-6 in ACC play. But their best non-conference win was against Seton Hall. A three-game losing streak against Duke, Boston College and Maryland in late February didn't help either.
Mississippi State - The Bulldogs (23-11) also have a bone to pick with the committee. Most of us thought late-season wins over Florida (which received an at-large bid with the same 9-7 conference record) and Vanderbilt, and a one-point loss to Kentucky in the SEC final sealed the deal. Apparently the selection committee didn't agree.
Mississippi - The Rebels (21-10) won four of their last five and has a victory over UTEP in non-conference. That apparently wasn't enough either.
UAB - The Blazers (23-8) ended their season on a three-game losing streak and were destroyed in the C-USA tournament by Southern Miss, 58-44, enough said.
Memphis - The Tigers (23-9) put themselves on the outside looking in after an awful loss to Houston in the C-USA semifinal. The Cougars upsetting UTEP in the championship game was probably the final nail in the coffin for Memphis.
Seton Hall - the Pirates (19-12) fell out of favor after losing a tough game to Notre Dame in the Big East tournament.
Cincinnati - Sorry Cincy, a 7-11 record in conference play is just too much to overcome.
*Note: Eight mid-major teams received at-large bids.
