her transferring is consistent with the modern era of players keeping their options open each season.
In previous years when a player wasn't quite ready as a freshman, they stuck around and improved and many of them became contributors as upperclassmen.
This is definitely coaches, players, or both leaning into the modern way of looking to the portal for the talent boost, not to development of returners.
Who knows, perhaps if she refines her game she'll be back at BYU for a finale season in 26-27.
