I've always said that if we plan well, we can keep the down time (or cliff) to 1 or 2 years.
2019 and 2020= 2 years, but really only 2020 counts, since we didn't rebuild or reset this year.
I'm being hopeful, but I realize 2022 or 2023 might be more realistic.
I do think, if we reset, build the farm for 2023 and beyond, and then spend large without making any mistake signings, we can compete in 2021. I'm not sure about being a top 4-5 contender, but I try to be optimistic.
