Ignoring the usage of results in your argument, I'm in favor of extending Stroman, but it's not a slam dunk decision. He's been trending in the wrong direction for several years now, at least in terms of xFIP.
2014: 3.17, 2015: 3.34, 2016: 3.41, 2017: 3.59, 2018: 3.84, 2019: 4.12.
That's not a trajectory you really want to see continue for another couple years.
