Saw him on campus today. This whole time I thought he was wearing a Wooly style neckbrace, i.e. just a big round piece of foam. Today from what I could tell it was plastic and more like this, although it had to have been a little smaller on the back and didn't come up as far on the chin, because it didn't seem as intense as this one. Saw him turn around to look behind him, definitely had fairly good movement but obviously not natural.
