I usually want teams that are fighting for a playoff spot, playing for every run, every out. Very close here tho, I might look ahead at off days and pitching matchups to make the final decision as none of these really stands out or deserves dropping
Laroche is the biggest gamble and I don't take chances with the playoffs. It's a matter of whether you want to play it safe or take the risk of laroche forgetting how to hit.
Why not drop victorino? i know he provides the most SB of those mentioned, but I don't see a lot of SB from your lineup anyway. PLus, Craig offers the multi-position eligibility with OF/1B. Plus, Victorino is performing just as badly in LA as he was in Philly before the trade.
