From the OP, this is my differences.
QB, only keep 2, Rush is probably out
RB & TE, agree
OL, keep 9, add Su'a-filo
WR, add Brown over Wilson, keep 6, but if they keep 7, add Johnson or Devin Smith or Wilson. Hurns or Austin could be a cut to save $$$. Then add Wilson. No way they keep 2 rookies if only keeping 6 WR's.
DL, agree, unless Gregory is in the mix, then who goes, unless they keep 11 for a short time. Hyder could be gone if he is not over his injuries, or Crawford cut to save some $$$
LB. agree
DB's, add Frazier, but a few players could push for spots overall. At CB, Olumba and Goodwin, at S Thompson.
