Well on the frustration side of things, it's probably fair to say I'm hand waving a lot of potential issues in that plan. Hoerner is at 93 wRC, Swanson at 83. So league average is probably a stretch, but those are still both guys that are going to comfortably end up north of 3 fWAR. We used Happ as a baseline of 120 wRC (his numbers this year). Bellinger is at 111. Busch and Suzuki are both at 126, which is barely ahead, and that K rate from Busch remains a concern.
Agreed you end up in a 10 guys for 9 spots situation bringing in an outside bat, but that's fine for me. It's basically 6 guys for 5 spots unless you want to fake it with Busch at second or third, but it's still fine. Trade for Tucker or Robert, sign Soto, there really shouldn't be an option that we can't work into the current roster.
