Given that there is a higher demand of sellers than buyers and the buyers don't have enough assets to give the sellers and thus the sellers can't rebuild and never contend
As a counter, why not starting with the new year allow 3 years of picks to be traded (So in January of 2050 you could trade 2050/2051/2052 picks), its some additional work but with the tracking thread (and I'd help do it if need be) i think it would provide an overall benefit to the league in terms of getting more teams active and competitive without 7 year rebuilds
