Nothing Facundo or Van Ness have shown this year indicates they have anything like that in them yet. Still a bunch of time to develop, but they're both very limited offensively. Facundo, in particular, is at a bear of a weight and I would have him as underdog to place. Van Ness is at an easier weight, but so far has shown to be more limited wrestler than Facundo (which is disappointing as a fan, since I think he has the most upside of any of the PSU young guys), and was recently relatively easily controlled by a guy I think most of think of as a bloodround guy in Max Murin. Haines, combining his ability with the weakness of the weight, is most poised to have one of those "PSU Freshman" runs, but I think O'Connor is a bear and will beat everybody, plus you have Andonian who is incredibly difficult to wrestle, especially the first time, and Robb.
I would think Haines has a decent shot to mid-to-high AA, but out of Bartlett, Van Ness, and Facundo, I think your more likely to get one AA than three high AAs; they're just too limited offensively. PSU guys have great records at NCAAs, but it's typically on the back of their superstuds, and I see that trend continuing (as they cruise to another title, so I'm sure they won't be complaining).
