Stascausky going to Michigan would make more sense than going to Oregon
That said there is a very clear path to early playing time for him here at UW (not sure what Michigan's OL situation looks like)
That said, the important thing for UW in this class is to upgrade their overall talent and depth and regardless of what happens at the top they will do so with this class.
While it would have been preferred to keep Ploog you could argue that the roster would actually be better served filling that scholarship spot by getting a more experienced player to replace Latu's role this year (see Arizona's roster) and then stacking another high-end TE in next year's class where there is a better separation vs DeGraaf from a class standpoint.
Stascausky is the most talented OL prospect in this class but the reality is that there's a good chance that UW needs 2, if not 3, OL starters to come in via the portal. In the event that he chooses to go elsewhere, that will only open up a roster spot for potentially a high end prospect in next year's class to feel like he's going to be able to step in and play right away.
With the portal there's always a path to covering your ass for any recruiting miss here and there.
