Plz plz plz plz no no Megan do not go to ISU!
In all seriousness though, I don't personally think it's likely. They could take her, but I'm not sure they need her. This past season ISU needed size at the post/wing more than anything, and they've already taken two transfers (Nyamer Diew and Beatriz Jordao) to address that need. Even with Feuerbach leaving, ISU still seems pretty set in their guard rotation with Ryan, Donarski, Espenmiller-McGraw (who was injured for most of this past year), and the younger Joens coming in off the bench. All of this isn't even accounting for their incoming freshmen. That said, ISU did offer Megan back in high school so it's certainly possible. But it seems she'd run the risk of ending up in the same situation she was in at Iowa--backing up Ryan at PG for a few minutes per half the same way she backed up Clark at Iowa.
I'd love to see Meyer go to Oklahoma--it would make another Iowa connection there and give me yet another reason to root for Baranczyk. Or any of the local mid majors you mentioned like Drake or even SDSU (who also offered her out of high school).
