REPOST from another thread but relevant here as well from a league setup perspective:
We have to make cap management tools available to owners to dig themselves out of holes previous owners have dug or ones they've dug themselves.
Otherwise, ppl get frustrated with the cap issues their team face and they decide to abandon the team.
To promote ownership stability and foster long-er term commitment to building winning franchises we have created these tools for owners to use. Call them loopholes but in fantasy play, no one wants to get stuck with too many problems that block them from contending. Buying out, resigning and applying for a Buyout discount are all cap management tools to help teams compete on the fly.
