It has been an organization wide problem for decades. Ricky held players accountable, but was allegedly fired in part because he team did not improve with fundamentals. Tony was supposed to do improve fundamentals and hold players accountable, but did neither. Unwritten rules bullshit (Yermin, Bean Balls) and taking care of his guys were the only things Tony cared about during his tenure. The team regressed in defense, baserunning and opponent scouting and game plans under Tony. Veterans openly stated they were ignoring Tony, were playing whether Tony penciled them in the lineup or not. Younger players followed suit. Eloy says f*** DH, it's for old fat guys (check the mirror Eloy). See also Moncada's "efforts".
Fans and media have blamed players for arrogance and reading their own press clippings (Tim "We're the best fucking team"), but the arrogance starts at the top with Rick Hahn. He had two smart moves in a decade; acquiring and flipping Adam Eaton, and convincing Jerry to pawn off the players inherited from Kenny to get a rebuild and several more accountability free years of employment via tanking/rebuild. Hahn has no demonstrable baseball acumen, ability to construct a roster, or hire people who can evaluate and develop players and trade/draft targets beyond Marco Paddy (also inherited from Kenny). Couple that with Jerry's arrogance and penny pinching that stole from Paddy's budget to save a few hundred thousand here and there on contract buyouts or trade acquisitions. Jerry also has starved the future pipeline by dumping a large portion of the scouting organization in 2020 and eschewing investing in analytics beyond hiring Tony's friend's son as a favor to Tony. Despite several years of high draft picks, the Sox farm system is once again bottom five in baseball.
The Sox are also bottom five in scouting, training, strength and conditioning, talent development, talent evaluation (internal and external), defensive positioning, analytics, draft performance, free agent acquisitions, fundamentals, defensive metrics, plate discipline, advance team scouting and opponent game plans. It's also a bottom five destination for free agents beyond players seeking their last contract with nowhere else to go. Players around the league talk and note the bullshit, be it the pre-tanking Sox with LaRoche and other crap, or the past few years with Tony. Same thing happened to the Bulls with Jerry overseeing the day to day, solid veterans refused to come despite cap space, the ones who did had no better alternatives (winning or basketball culture) due to the dysfunctional incompetent organizational mess over the past few decades.
This is a reflection of Jerry. his permanent FO righthand men, and his crony managerial hire that blew up in his face.
Pride goeth before destruction, and an haughty spirit before a fall.
Proverbs 16:18, KJV
Go Blow Rick!
