Still don't understand why there would be any interest in Kimbrel, let alone any way in which a guy who pitches 60 innings replaces a guy who gets 600 ABs. If you sign Kimbrel, Neshek probably gets traded (or Hunter, and it's debatable who is better, and one of them is probably gone anyway). And Arano might not even make the team full-time (since he has options).
If they do lose out on Harper I'd rather go for Keuchel, who addresses a legit existing weakness (no LH starter, four of the five starters are not sure things. Keuchel is not either but he'd up the odds). The pen is already fine. And how many championships did the Yankees win in the last 10 years because of their monster bullpen? They haven't even made the WS more recently than the Phillies (though they did win that one).
And how is Harper a mercenary? If that's true then he just spent the first part of his career as a slave. He's a guy looking for a job who thinks he has a certain market worth. And the Phillies obviously agree or they wouldn't have punted on Manny. If he's not, great, they will get him cheaper like they did with Arrieta.
Would love to think that, between them, Haseley and Moniak and Williams can produce even one guy who would seem blocked by Bryce Harper. But if Haseley or Moniak aren't CFs they have likely already failed a little bit. The whole reason why the Phillies are so hot for Harper and were so hot for Realmuto is they already decided that the system they inherited and the drafting they have done so far isn't as promising as it should have been.
