The team roster provide a flat dimension.
E.G 2021 Reinhardt Distribution by Position
Upon looking at the team roster turnover, you will be able to understand and estimate number of "new" freshman on the team.
Team Roster Turnover Outgoing (how many players from 2020 are not on 2021 roster)
Team Roster incoming identifies new players, note you can see a lot of freshman in the Total incoming column and 1 freshman in the incoming transfer column.
This means there is a player on the roster listed as a freshman that transferred in.
Team Roster Turnover Incoming (New Players) by position
This is the starting point.
