I voted OL because I believe that if Penn State can develop a genuinely solid OL, the offense could be really explosive next year. Thorpe is supposed to have that "nasty streak" James has mentioned as lacking on the previous OL , so I think CJ will start at OG.
At the DT positions, PSU does return Windsor, Jordan, Mustipher, Barber, Hawkins and Culpepper. That is 3-deep there. Add in whomever James signs for 2019, and DT will at least have 7 or 8 guys from which to choose. I think both Culpepper and Hawkins were 4-star recruits by at least 1 service; by September they should be large enough to handle playing time.
