Even if they move off some of their vets on 2nd or 3rd contracts, the younger guys on rookie deals who would most likely replace them aren't exactly trash. Trade Cook, he's replaced by Mattison on the last year of a rookie deal who has already shown he could start in this league when Cook is out. Trade Thielen, he's replaced by KJ Osborn who just put up 700/7 seeing like 60% of the offensive snaps. Have a promising LT on a rookie deal, a good young RT on a long term deal, obviously one of the best young WRs in the game, and they get their highly regarded TE back next year who was going to take the next step this year before injury in Irv Smith.
Just hard to see them moving enough talent to truly be bad enough to "rebuild". Can't rebuild in mediocrity.
