You may want to actually read it more carefully...
If an incoming player has enrolled in summer school,
and then that player’s head coach leaves the school before the start of the fall term, the player can transfer freely.
Most coaches aren’t moving around in the summer, with most sports out of season, but there are a few late surprises every year. And under this new rule, if, for instance, Ole Miss’ head football coach got ousted in July after phone records tied him to an escort service, then every incoming freshman would be allowed to go elsewhere and play.
The NCAA’s initial press release on the matter suggested
that all players on the roster would get this privilege if the coach left in summer. It’s not clear why they shouldn’t, given that those players likely agreed to play for the same head coach an incoming freshman did.
So while it applies to all players her coach did not leave in the summer matter of fact she got fired before the end of the spring term.
I don’t think this automatically makes her eligible by the letter of the law. Now can she get an immediate waver yes but not by definition of that new rule the other rules refer to grad transfers and walk-ons to which she doesn’t qualify as either of those.
