The needs to me look like this, not in a particular order:
Middle of the order bat, which can come from CF, 1B, DH, 3B
Playoff SP, by which I mean a SP you're good making more than one start in a playoff series(I find this a better mental model than debating #1 v. #2 v. #3 SP)
A second above average bat (~115 wRC+) from what's left of CF, 1B, DH, 3B
A leverage reliever
There's permutations where you can add other minor things to this(a RHH CF, another RP, a C), but those are the highlights.
If you bring back both Stroman and Hendricks, unless payroll is going to be significantly higher than expected(like flirting with 40 mil above the tax line), it's tough for me to say Playoff SP is any higher than 3rd in priority. That said, Stroman and his contract (at least most of it) are likely easy enough to move that you don't have to stop pursuing a playoff SP just because you have both of them banked. But the paths to getting one without the acute need do get more narrow.
