Sure, maybe they are. And you can do both, but when you’re building a program, potential one year rentals don’t make as much sense as a potential younger talent you can build with. In Austin’s case, Ole Miss knew for sure they would have her for at least 2 years versus one. Obviously you can’t fill an entire roster full of freshmen but there’s also no guarantee the portal will yield you anything either.
Regarding recruits, I had heard LSU was going after Mallory Collier pretty hard and ended up missing out. Grace Van Slooten isn’t a 2023, but she’s a 2022 Kim was going after hard at Baylor and she ended up having LSU in her final 3 when Kim moved there. She went on an official but ultimately ended up committing to Oregon. From what I’ve seen Williams also seems to have a pretty good relationship with Ole Miss.
Even with the other 2023s they are after, you are undoubtedly playing catch-up with other programs. That already puts you at a disadvantage. If you get Jackson and she leaves after a year, that puts you in the same position this time next year…..which is the original point. As talented as she is, considering how long you might or might not have her and some of the alleged issues it might make more sense to prioritize athletes you can build with long term.
