Yeah, I remembered someone talking about a waiver being impossible. I'm sure you know more about the NCAA's rulings on these situations than I do, but I'm inclined to say that Soares's situation is unique enough to at least make it worth trying. The combination of playing in NAIA, sitting out injured in the COVID season that didn't count against eligibility, then transferring to the NCAA to play a single year and getting injured just a few games after the threshold for a medical redshirt seems like pretty special circumstances. I don't expect them to make an exception, but it seems like if they were going to, this would be the situation to do it.
But like you said, she still should have a good shot at getting drafted. It would be perfectly reasonable for her to pursue that rather than even try for an unlikely waiver.
