Seems like we should be clear on what measures we're discussing regression. From a BB%, K%, HR% and FIP perspective, I think most of us agree he is likely to regress somewhat (although hopefully not too much!). From an ERA perspective though, it is completely reasonable that he might improve, given better outfield defense throughout the year (although even with getting rid of YesPig, with Hunter now, that is not a given). I only say this because different people evaluate how good a pitcher is on different metrics. So people who give more credence to the former stats (myself included) may say Hughes is very likely to regress, while people who focus on ERA, innings pitched, and even W-L might be more likely to say he's not a big regression candidate. That being said, I'm still a big fan of the extension, even though I think he is likely to regress. If he even comes close to what he did last year in 2017, 2018, and/or 2019, it will have been worth it.
