The tourney expansion is old news but the format of the expansion has not been confirmed to my knowledge. It would seem like the most likely scenario is that there will be four play in games now instead of 1 and that these games will consist of the 8 "worst" teams in the tourney with the winners advancing to play the number one seeds.
I, for one, would not be impressed. The 15 and 16 seeds don't have realistic illusions of advancing very far in the tourney. However, they undoubtedly look forward to the opportunity to play against the top teams in the country. Alas, under the current format, one of those teams is basically told, "Yeah, you earned the right to play in the NCAA tourney.... but not really." So now, instead of one team getting the shaft, four teams will be in that position.
I would much rather see the "bubble teams" forced into those play in games, with the winners earning the 12 seeds. This way, those 15 and 16 seeds (whose only hope of ever making the tourney is winning their conference post season) will still get the chance to run with the big boys, while the major conference bubble teams will be forced to play eachother for the right to play in those always intriguing 5-12 matchups.
Sorry (but not really) if this seems random. I heard some dicussion on the expansion earlier today and so I was motivated to get out my soapbox.
