Being as RR himself stated he didn't care to use analytics as much as they(FO) would like and the reported tension in that I don't see how Hahn letting him go to try to find someone more willing to use analytics in real time (in your words a "yes man") is him reaching for power.
Things change very fast in this league, there's no doubt he'd be able to find another GM spot in a few years especially if the Sox has some success which is pretty hard to imagine they don't at this point.
Hahn has a job for life if he stays but I sincerely hope he goes into "idgaf" mode and starts wheeling and dealing to give this window a legit chance these next 2-3 years then leaves
yea thus the pain comment. there's just no way you can convince me this is the right move. JR should be opening his wallet no matter who the manager is, miss me with that "logic".
