I'm all for adding at least 2 more significant players before opening day- preferably a CF'er and a closer, but another SP'er couldn't hurt, either.
I do think the main prize is still 2022 and beyond- not 2021, and we should not so anything that hinders our chances or positioning in 2022.
I'm not sure how important staying under the tax line is for our longer term outlook. It seems like gaining one more year of lower taxes will allow for more spending down the road, but adding a bunch of one year players and trading them for prospects at the deadline could help much more than tax savings, and who know, maybe a miracle happens and we actually put everything together and make a strong run at 2021, however unlikely those chances look, right now..
