Yeah I think it has some real compounding effects in a positive direction:
- You're getting a direct upgrade by more or less replacing Hendricks with a guy you expect to be 2.5-3 runs of ERA better
- Like you said you're bolstering the pen, I'd anticipate Wesneski and Assad there, the former in short relief the latter in long
- The opening day Iowa rotation, even with the above assumed in the pen, is Horton, Birdsell, Noland, and whichever of Brown/Wicks doesn't get the 5th starter spot
- I think with that level of depth, you can more comfortably hunt for upside with that 5th spot and give it to Brown and take a big swing to try for star caliber production
- While we've seen how quickly pitching depth can fade away, assuming the veteran we bring in doesn't have notably scary medicals you can probably afford to trade one of the pre arb SPs. Including an MLB ready (or damn close) SP is a really good way to differentiate a trade offer to either win a bidding war or potentially convince an obstinate southern California GM to stop being a wuss and make a deal already
