Pretty sure VV gets non-tendered no matter what. There is still probably a chance he comes back at a lower guarantee, potentially with incentives.
In terms of money they do have a little more to play with. $65 million from Arrieta, Didi, JT, Robertson, Bruce, and VV. Likely arbitrations are Eflin, Morgan, Hembree?, Knapp, Hoskins, Seranthony. Assume they non-tender VV and they can probably do all of that for around $10 million.
I guess whether they could add bullpen help depends on whether they could get a starter for closer to $15 million rather than $20 million. They won't be in the Trevor Bauer market but I was assuming Stroman was a guy they have liked periodically in the past. He was going to get $20 million AAV before this season, but not as sure about that now.
