@baseballhs IMHO there are a couple of events that we would need to look at regional, conference and school level.
Note, the challenge with the portal is that is doesn't contain position and grad class. I didn't have time to add that those tags to this year's data
That being said:
The easy events are:
- HC Changes (to date 42 changes) - school level (we can ignore some of the latest changes)
- Decrease roster size (40 to 35) - school level
The draft and free agent signing are a little bit more nuance.
History of new commits: New joiners (high school, JUCO pipeline)
Regardless of what is happening now, the question is how does the coach normally manage his roster? What are the fact patterns?
I don't know if conclusions can be drawn based on previous history, but it might a interesting research project.
IMHO, next year's spring roster will shed some of the light on this, but will also need some unstructured data, e.g survey to provide the appropriated context.
