I'd take McLouth easily. I don't see Ethier having such massive upside to suggest he's a better keeper than McLouth when McLouth himself could hit a bit for power and add some SB (I expect the SB total to increase for Nate). If Manny stays, then I'd say that's more reason to punt Ethier away unless he improves hitting against lefties and with the way Joe Torre handled the crowded OF situation.
