So, after some research, here is my understanding. First, the NCAA pays for all travel for teams in the tourney. Th antiquated theory is that the cost will cause less teams to participate if they had to pay for it themselves. So since they are paying, they try to minimize costs.
Second, if you can drive there (within 350 miles) the cost is less to the NCAA (bus versus plane) so we are going to put you where you can drive. So Louisville and NC State if still both two seeds go to Ft Wayne and Greenville respectively.
Third, the rule against two teams from the same conference being the 1 and 2 seeds in the same region comes into play. Hence, Stanford has to travel. Line this all up and we go to Portland unless there is a change in Louisville as a 2 seed. Charlie Creme( "ABC Charlie"- Anybody But Connecticut Charlie) doesn't think anything changed yesterday. Look at it this way, we would have to beat Oregon anyway to win it all. I also think, because I am a cynic when it comes to the NCAA, that they would like a UCONN v. Oregon regional final for TV ratings.
