Maybe they are not operating with a ton of cap room however they will do what is best for them, not for Peppers. The NFL is business, teams need and want to get better. If they can get a higher draft for him, they will make sure it's done.
Teams that would pay for that player are teams like Buffalo, teams that are in desperate need for a DE. I am sure that the Bills could figure out how to get Peppers his money without killing us.
