In earlier versions I'd advocated, and still am, for a manager's style or preference selector beyond our present slider system and designed/dedicated specifically to lineups and substitutions, the latter affecting the former. Arbitrarily, let's just say provide a choice of: Offensive, Defensive, Balanced, Positional, Speed/Power, etc... Frankly, I don't what they'd be called, but allow the opportunity to dictate, or at least guide the substitution and lineup creation (that is, GMing it, not manually doing it) so there can be a reasonable expectation of results. Not perfect, mind you, but reasonable. Sub? What's the philosophy/preference? Defense (regardless of inning). Put in the best available defensive player, then. Sub? Positional. Shorstop out, then shortstop in and he'll PLAY shortstop in the lineup. Etc.... Lot of design work, but I do think there's merit for some future version.
