2022 Player Attrition (First Glance)

Hey CBI, that's a nice list.  Thanks

Where are you finding the Fall 2021 roster information on all those schools?  Some schools have already posted rosters to their websites, but many that you have listed have no current info posted. Do you have a secret source?

Ah - I think I see the issue.  The link posted defaults to the 2021 Year, which means last years rosters.  If you change the year selection to 2022, you see the current roster info, and this selection is showing far fewer teams with their rosters already posted.  Makes more sense now.  Thanks again.

Yeah. My bad.  Currently we still consider 2021 as the active year. In the past, we've only posted spring roster, which normally are available ~ feb/mar.

With Covid thought being able to project rosters would be interesting.

If other school make there info available, will then post.

There are some schools that we consider demo schools, that will allow you to drill down on the details, e.g Mississippi State.

I have several questions:

1)  The attrition rate, does that include those that graduated?  Graduated early?

2)  If based on fall rosters, is your data looking at only previous freshmen, sophomores, and juniors?  Does it take into effect those juniors (and sophomores) that were drafted? 

3)  Why is Notre Dame an anomaly?

Answer 1 and 2: Player attrition equals the how many players from previous year are not on the team in current year. Since the fall season is a precursor for 2022, it has been loaded as 2022 data.

Answer 3: Compared to who?

Here is the feature in detail.

Based on 2021 fall roster, Notre Dame had low player attrition

Below shows difference between spring (2021) and fall, with potential reason for attrition.
