1) Catcher who complements my primary catcher; usually my second catcher is excellent defensively and doesn't totally suck against LHP.
2) 4-5 guys, 2 up the middle and 2-3 other, who either (a) are viable reserves to play every day for a while in case of injury, but get a bunch of ABs from resting my starters, (b) are platooning with a starter (and I platoon a lot), or (c) have a key skill (usually an élite glove and/or baserunner) that get them playing time in specialized situations. I'll always have a couple each of (a) and (b) but if my starters are good defensively I can go without a (c).
