I absolutely believe that they would need to be at least a 3 and maybe even a 2 to get that advantage. Today means nothing as it costs them nothing and actually helps generate discussion and coverage. But, I have a better chance of dating a Victoria's Secret model then the committee allowing us as a 4 seed to play 1 seeded Duke in Newark.
This is my larger point.
I use the Syracuse 2003 run as an example. They won the BE regular season with Pitt, Pitt won BE Tourney and got a 2 seed. Cuse was a 3 in the East. The East Regional was in Albany. And sure enough they matched up with no. 1 seed Oklahoma in the Final. I mean that building was ALL ORANGE. It was so unfair to Oklahoma.
