I am a "best player available" truther, but just looking at more mocks/draft evals, I really feel like DL in round 1 and RB in round 2 should be the move. You still have the potential to get best in class players at those positions with picks 20 and 52 (although it seems DT Mason Graham and RB Ashton Jeanty are consensus top 10 talents at this point).
Kenneth Grant and Walter Nolen seem like the next tier of DT's and are projected to go around pick 20.
One of Omarion Hampton, Judkins, Henderson, or Kaleb Johnson should be there with our 2nd round pick as well. I've said this so many times but pick ~50 really is the sweet spot for RB's and Centers.
