Drop Rice. Pickup Maroney. Maroney will be more useful down the stretch.

Somebody in one of my leagues just dropped Laurence Maroney. I know that he can't be depended upon as an every week starter but he's definitely not ww fodder. I'd like to pick him up but am having trouble figuring out who to drop. My leading candidate is Ray Rice. I have McGahee but I'm still not sure what Baltimore's RB situation is going to look like.

So is dropping Rice, who I have handcuffed to McGahee, to pick up Maroney a good idea or not?
