Still, even if that is true and you trust in 2021 breakouts from Nestor Cortes Jr., Clay Holmes and Jonathan Loaisiga, the Yanks should not fixate on just improving a positional core with more athleticism, defense and contact skills — though that obviously is Job 1 of the winter.
The Yankees’ rotation has depth and talent, but enough uncertainty that it can use one more piece. Zack Britton (likely to miss all of 2022 after Tommy John surgery), Aroldis Chapman and Chad Green will all be entering their walk seasons, and though the Yanks have a nice core of pen arm, for 2022, one more trustworthy, late-inning piece with control beyond next season would be helpful.
