Again - it's just conversation as this trade isn't happening. But lots of pitchers simply fall off a cliff and never come back. Aaron Sanchez (7th in Cy Young voting one year) and Ricky Romero come to mind for Toronto. Obviously you'd like to shoot higher in your return than India. I agree his peripherals don't suggest a ton of upside (although this year they are a lot close to 2021 than 2022, which is good), but he was the ROY in 2021 and the 5th overall pick in 2018. He as a pedigree.
I'm not sure it's true that it's easier to fix pitchers than hitters. I could be though. I just thought it was interesting as Merrifield is a FA after this year, Espy/Biggio suck and while we have guys like Barger/Orelvis/Schneider coming along - we also need to replace our 3rd baseman after this season and well, it's highly possible that 2 of those 3 will be useless (and a possibility all of them aren't ML starters).
