Definitely wouldn't take the risk with Rice, but if you could afford a couple weeks without either, I'd look at Collie. Harvins value is going to plummet, I fear, while there's plenty of room for Collie to still produce in Indy once he gets back. Especially with Dal, Ten, Jax, Oak weeks 13-16 (I'm assuming your playoffs are in there), Collie should be a valuable asset during the playoffs.
