There are a few 4 and 3 star defensive/ath recruits that could be of interest, but that's without knowing if any are legacies. Most appear to have that northeast/east coast footprint so I'd have to think that Penn State would be able to retain most if not all of them.
But never say never, and Shoop might be able to lock in a few as-yet-uncommitted Vols targets if he's hired.
