I found this from a Oregon Ducks September article post the Sedona commitment. Sure seems like Graves is pursuing Hailey Van Lith knowing his scholarship limit. They were communicating they had room somehow at that time.
“The Ducks have basically reached capacity in their 2020 recruiting class. The top-ranked class features five five-star prospects with guards Sydney Parrish, Maddie Scherr and Te-Hina Pao Pao and forwards Kylee Watson and Angela Dugalic already verbally committed. In the past I've mentioned the possibility of adding a sixth player to the class. Right now, that remains possible, but the only remaining target is elite point guard Hailey Van Lith. Oregon and Van Lith have an open dialogue about tripping her this fall. This is a decision that will be made in the coming weeks. In order to land her, they'll have to beat out the likes of UCLA, Louisville and Baylor. A decision for a trip remains up in the air.“.
