That was definitely the full Fangraphs/pitching ninja treatment. I do get the argument stuff-wise that he is a unicorn. Most of the guys like him throw 95 and not 100. He seems to have the type of slider also where the break is so great that the chances of him being taken deep on a hanger are less than other pitchers.
I would still tread carefully. Probably limit him to every other day and no 2-inning outings. One can do that in the playoffs and frankly we have 5 or 6 late inning arms now. In tentative pecking order I think I rank them: Kimbrel, Alvarado, Hoffman, Strahm, Kerkering, Dominguez, Soto. All one could say about that is wow - 7 arms that could potentially close for many teams. It is a far cry from Neris and close your eyes on the rest of them that we had a few short years ago.
Kerkering could be the most effective of the 7 now but the main point is we have 7. If starters only go 5 or 6 innings we are fine because we'll have a couple of long relievers too in Sanchez and Lorenzen before we get to the 7 late inning arms. We also only developed 2 of these arms. Not ideal so it costs us a little more $$$, but this is a major league playoff-ready bullpen.
