You don't 'upgrade' clear best 22 players, it's poor list management.
i.e You don't trade out Gus (and picks) for Cerra, even if Cerra may be a 10 or 20% upgrade on a wing. Exchanging one decent best 22 player for one good one presents a negligible difference unless you're talking about a generational type of talent you're getting back in return who will be in your top few players.
You trade out picks which are unknown quantities which you never truly 'owned' in the first place ideally - which we won't have.
FWIW, I'd rather find the next untapped Langdon, or Amon for a 2nd rounder than pay an absurd amount for a player whose reputation largely lies on being taken at pick 5 a few years ago.
