I think a lot of Harris's major league decisions are more or less made for him by the circumstances he finds himself it. He can't sign Hall of Fame- or All-Star-level free agents if there's someplace else they'd rather go, and at this point there always is; he can't trade for controllable All-Star-level players without giving up at minimum Max Clark, the only player who could conceivably unlock such great players in trade; he can't trade for blue-chip prospects without giving up Hall of Fame- or All-Star-level players we have, of which there is one and perhaps (or perhaps not) two; and he can't simply pick up everyday regulars and above average pitchers off the waiver wire or the minor league free agent pile, or else trade our dregs for guys like that other teams will make freely available in trade, unless he gets good and lucky.
All that really leaves Harris is to develop the talent we have in house already and hope it works; as well as draft good players and sign good international amateur free agents in the future, develop them, and hope that works. And if/when we get enough of those players developed and we have enough of them helping us win at the big league level, then we'll be in a better position to make trades for actual really good players as well as make Detroit a more desirable destination for actual really good free agents. Because in this game, there's no escaping it: you have to get good first before you can get a lot better.
I acknowledge this mightily frustrates most of the posters here who will tell us it's not their job to know what moves Harris should make because they themselves don't work in front offices, but damn it, Harris does, so he should just make awesome moves happen. And for a fan, that's a defensible feeling, and actually, they don't even have to defend that feeling. That's part of what being a fan is all about. But just because a fan demands Harris should wave his magic wand or else find another job, that doesn't make it a reasonable benchmark by which Tigers ownership should judge Harris's performance, and thankfully, this ownership does not use that benchmark. So vent away and call for his head (and A.J.'s head) all you want, because it's not going to happen anytime soon, and I'm fine with that.
