Phil, I'm not quite sure I understand the reasoning. I thought that the S-curve referred more to the snaking level ideal of having the #1-#8-#9-#16 for instance seeds together for the 34 total (not that it ever works out that way exactly) rather than any real significance of how the top 4 seeds should match up #1 vs #4 and #2 vs #3.
And I'm not understanding how the Regionals hosting and any marketing considerations would reflect on how that last FF weekend is matched up and what would set up say a #1 vs #3 and #2 vs #4. Can you explain that concept more?
The rationale behind the S curve is that the best teams should get the easiest opponents. That can be viewed as a three step concept:
- The 1 seeds get to play the 16 seeds 2-15, etc,
- The allocation of the 1 and 2 seeds such that the overall top team should play the overall 8th best team, and
- When setting up the regional format, the top overall seed should meet the 4th best in the semi.
The first of these three steps still applies, but the second step has definitely given way to costs/geography as a consideration. (which is why I advocate that we should stop calling it the S-curve. Step 1 doesn't require the "S".)
What is less clear (to me at least) is how they handle step 3. Geography plays a role in step 3, but not step three, after all they are all going to the same place. Do they return to the S curve concept - i.e. match up the overall 1 versus 4? Anecdotal evidence suggests this is not the case, so perhaps TV considerations, either timing or desirable match ups, play a role. That what I meant by marketing considerations, that they might identify the best match ups form a marketing point of view, rather than automatically pitting 1 against 4.
As for regionals hosting, it throws a spanner into the works. For the first (and only) time, you can have a team playing a regional on their own floor, while not being a 1 seed. This is certain to happen with Nebraska, and may happen with Louisville. Now the committee has the additional complication of deciding how to factor that in. When they decided to make location the primary consideration in step 2, it meant the possibility that the overall top seed got to play someone other than the 8th best team. That was considered a small price to pay. But now we have the distinct possibility that you not only ask the top overall seed to play the 5th best team, but on their home court. I think it is possible they will decide this is a bridge too far, and will allow considerations other than pure geography in step 2.
