It's as much an annual Selection Sunday tradition as grabbing a pen and paper, turning to CBS and marveling that longtime host Greg Gumbel never seems to age. First the bracket is unveiled. Then the bellyaching begins.

The MAAC champion Gaels apparently earned that bid because their 25-7 overall record and 15 wins away from home outweighed the fact that they did not defeat a single RPI top 50 team all season and the best team they beat was Saint Joseph's. If players from Iona, NC State and South Florida exhaled in relief when their schools' name appeared on the TV screen Sunday evening, a handful of other NCAA tournament hopefuls were not as fortunate.

The Huskies won the Pac-12 with a 14-4 record, but it wasn't enough because of the weakness of the league and their own non-league woes. Washington failed to beat a single RPI Top 100 team out of conference and also lost at Nevada and at home to South Dakota State. More...
