One thing that strikes me about these numbers, if I'm reading them right, is that in most cases, the number of new (transfer+freshmen) players is more than half the total team, or even close to 2/3 of the team.
I guess I would have expected it more like 1/3 (assuming that seniors are draft or done). The only ones below 35% are Notre Dame, Boston College, Penn State, Michigan, Stanford, Washington, Vanderbilt, and Florida. In the Big 12, no school is below 50% new players.
That means that a lot of upperclassmen are leaving, whether cut or by choice.
