I highly doubt 2008 Miami (#1 national seed and 47-8) had an RPI in the teens
I don't believe most of this data. In just pulling 2008 data, Florida State and Miami both look like they had Top 5 RPI's. The UC Irvine datapoint looks like it could be valid. But sometimes it's hard to know if the RPI data is what it was at the Selction Show, or if it kept computing as the postseason played out. But even if that one is legit, the committee has sometimes given some RPI leeway to the West Coast due to some inherent disadvantages they have.
But I still contend there is zero historical preference in the "National Seed" era of an SEC or ACC champion with an RPI of 19 or higher being given a national seed. It's uncharted territory and it will be interesting to see how its treated. If the season ended today with their RPI at 19, I think they would be seeded 9th or 10th overall. The eye test says they are a national seed. But you rarely see the commitee deviate THAT far off of RPI (An 11 slot jump) for a national seed or host site.
Further demonstrates that Georgia could conceivably be left out of the national seeds if their RPI does not improve. As we can see here, low RPIs don't get in too often. UC Irvine might be the anomaly.ChatGPT say Miami in 2008 was #1. Proof that ChatGPT is not extremely reliable.
Think someone else that they got a very easy SEC draw. So this all makes sense.
