In response to previous link with very flawed ratings for the strength of the regionals based on average rankings of the 4 teams, I went full nerd and made a revised ranking in a way that makes more sense….just comparing the difficulty for each of the host teams. Same methodology could be done for 2-seeds, 3-seeds, or 4-seeds, but since we’re a host, I wasn’t super concerned about that.
For this, I used RPI as the base metric. You could also use ELO, DSR, or whatever instead. The most glaring observation - there is a HUGE variation in the quality of the 4-seeds. The best RPI for a 4-seed was 82, the worst was 239. This shows some 1-seeds essentially have an auto-win, where others very well may be in for a battle.
Conclusion - cannot just apply a floor to the 4-seed metric in the calculation. But, you also can’t give it equal weight to the 2-3 seed metrics. I decided to do a weighted average, in which the Mid-seed average rank comprises 80% and the 4-seed rank comprises 20%. If I were to try and compare 2-seeds or 3-seeds, I’d probably weigh the 4-seed rank a little more heavily, like 30-35% or something. As an aside, there were also some alarmingly bad RPI’s for some 3-seeds. Some were in 60’s and 70’s.
The results are below, ranked from easiest regional for the host, to most difficult. The +/- values in parenthesis show where the difficulty rank falls relative to the host’s overall seed. Example - MSU is +4, meaning we have the 10th easiest regional even though we’re the 14 seed (favorable draw).
