I mentioned 1 year deals that would bridge us to the hopeful return of Sale and maybe even ERod & Eovaldi's better chances at doing well in 2022 more than 2021.
Then, as you suggested, we make the big splash SP'er addition.
Yes, it wouldn't hurt to add a durable SP'er, now, that could help in 2022 and maybe beyond, but that could be something we do in 2022, as well.
I'm not seeing many capable and durable SP'ers on the market, right now, and I'm not big on building a winning rotation by seeking out good 5th starters.
