My view about the "strategy" argument is that it is an artifact remaining from an older model of fandom in which fans identify with the team's manager, and thus invest things managers do with greater significance — pitching changes, pinch-hitting, calling plays (sacrifices, hitting and running, etc.) — than perhaps they really deserve.
I identify — and I think most here do, too — more with GMs than managers. (I suspect the popularity of fantasy baseball is making this approach to fandom more widespread.) Roster construction has the interesting challenges, while for in-game strategy, I basically just consult The Book, and tend to assume that any variation from the approach espoused within is due to factors we don't know about. I don't get too worked up about hit and run decisions, but I care a ton about the draft.
