I just look at the Sox v. the Padres. Started the rebuilds at the same time; both had made failed "go for it moves" a couple of seasons before. The difference is that Preller mitigated his losses; Hahn didn't. That put Preller close to an even start with Hahn despite Hahn having so much ammo to trade. Then of course, he schooled Hahn in the Tatis trade; it's not surprising as Preller spent years in the weeds scouting talent, while Hahn sat in an office. And beyond Tatis, the difference is striking.
The dismal record, the failed 2013-2016 effort; the scorched earth disaster in June 2016.....and being so far behind the Padres. Devotion to lifers, hiring buddies, failure to modernize the front office with analytics. When is enough enough?
