Parker Jr. has played very little time on defense after a solid sophomore season playing DT and getting a three-star rating for a 2018 player. Instead he's moved over to OT and he's as good if not better at OT if you asked me. Lots of upside regardless of where you see him on the field. He has an offer from Missouri (was once committed too), he's also visited, and I would consider Missouri one of the top teams to possibly land his services.
