Other than the names mentioned...it feels like keeping Giolito together with baling wire and duct tape until he could really get paid (well, almost $40 million) is one of his most significant accomplishments.
Because his Red Sox 2024-25 contract numbers certainly weren't based on his brief time with CLE and LAA.
When all things are considered, one would say Katz pretty much deserves a "neutral" rating and that the next 2-3 seasons will be his truest test of all.
Even then, other than Schultz, he's lacking a slew of "top" pitching prospects, so approximating the Guardians/Brewers/Braves in terms of major league development would be a massive crowning achievement.
This "exercise" is not unlike trying to assign Marco Paddy a grade without taking into consideration JR's pocketbook controls, the supposed underage ban in the org and what actual resources were made available to him...you'd have a difficult time isolating exactly how much he's even responsible for the last 5 years or so of limited upside Cubans after the "Connection" had already worn out.
Alexei Ramirez, Abreu, Robert, Jr., and Tatis, Jr., pretty much amounts to a lifetime contract/tenure.
Plus, he's never been directly tasked with "fixing" the Dominican, and that's probably one of many reasons the Sox are still struggling there 15 years after Wilder.
Yes, two wildly different debates, certainly...but the tentacle-like influence of JR, TLR, Hahn and KW touches nearly everyone, doesn't it? And it can't easily be separated in any easily quantifiable way.
