Which is a good argument for keeping Kapler! I still mostly agree with AF (though not about Keuchel, he wasn't asking for multi-year deals in June), the season was not a failure and if Klentak believes his plan his manager should get a third year, because they will win, and everyone will be back in 2021 too. If he doesn't believe in his plan having him change to a new one isn't necessarily a good thing. If the plan is already thought to be a failure than yeah, fire Klentak. Arguably the plan has only failed because the expectations changed.
But clearly this is not a team that's about to change GMs, barring a big surprise. He's probably already interviewing replacements for Almaraz and his development director just made a ton of personnel moves. If there were going to be even bigger changes you'd want the new person to make them.
Clearly in hindsight the Phillies should have signed Keuchel. But on June 7 they were 11 games over .500, had just won three games in a row and still led the Braves by two.
Zach Eflin was 6-5 with a 2.88 ERA.
Arrieta was 6-5 and his ERA had only just started to climb (it was 3.60 on May 25).
Pivetta had already returned from AAA and made three very good starts, including that complete game.
It was completely reasonable to think they had enough starting pitching to get through the next six weeks, at which point they would have traded for Greinke or Ray or Boyd. The only reason to prefer Keuchel was there was no trade price, but a younger or better longer-term acquisition would have been worth it.
