I think they will move away from RM's input on player acquisition. Paea was playing well but the Thorton issue was odd and seems related to coaching. They did have 2 season ending injuries at the position which would put any team in a bind.
They did have some 1tech types rated fairly high on their leaked draft board a couple of years ago.
Dontari Poe at 1-year, 8M would have been a great fit. He'll be a free agent againt next year. Frederick and Martin have struggled with him more than most DTs over the years.
Star Lotulelei is a free agent after the season.
